Hyperbole and emotionalisation: Escalation of pragmatic effects of proverb and metaphor in the “Brexit” debate

(How) Can the use of hyperbole in metaphorical idioms and scenarios contribute to an increase in emotionalisation of public debates? Using a research corpus of quotations from British politicians’ speeches and interviews and of press texts 2016–2020, this paper investigates hyperbolic formulations in Brexit-related applications of the proverb ‘You cannot have your cake and eat it’ and related scenarios of national liberation, which appear to have strongly boosted emotionalised public debates. For instance, Brexit proponents’ reversal of the cake proverb into the assertion, ‘We can have our cake and eat it’, and their figurative interpretation of Brexit as a war of liberation (against the EU) triggered highly emotional reactions: triumphant affirmation among followers, fear and resentment among opponents. The paper argues that the combination of figurative speech (proverb, metaphor) with hyperbole heightened the emotional and polemical impact of the pro-Brexit argument. Whilst this effect may be deemed to have been rhetorically successful in the short term (e.g. in referendum and election campaigns), its long-term effect on political discourse is more ambivalent, for it leads to a polarisation and radicalisation of political discourse in Britain (as evidenced, for instance, in the massive use of hyperbole in COVID-19 debates). The study of hyperbole as a means of emotionalisation thus seems most promising as part of a discourse-historical investigation of socio-pragmatic effects of figurative (mainly, metaphorical) language use, rather than as an isolated, one-off rhetorical phenomenon.


Introduction
The concept of emotionalisation implies a heightening of emotional intensity, as defined in psychology and also in an approach to linguistics that is interested in the "emotive" and "interpersonal" aspects of language (Alba-Juez & Larina 2018, Jakobson 1960, Halliday 1978, Mackenzie & Alba-Juez 2019. It presupposes a basic 'given-ness' of emotions in discourse and focuses on their escalation to a higher degree of outspoken-ness and/or crassness, perhaps even reaching the realm of taboo (Allan & Burridge 2009, Bednarek 2019. Political discourse provides many examples of such emotionalisation, because its contents are usually controversial and because its participants, e.g. politicians and media, compete for attention and approval from, the public and have an interest in surpassing each other in expressing emotionally charged attitudes towards and judgements about the respective topics. A high degree of emotional intensity is thus a characteristic of public polemic but it can always be ratcheted up even further. Its analysis thus entails an explanation of how a given emotional aspect of language use is further escalated. In this article I will investigate the role of hyperbole in emotionalising communication in politics. Since Antiquity hyperbole has been well-known and studied as a rhetorical trope (Lanham 1991: 86, Lausberg 1984: 74, 138) -even Aristotle (2000.16) connected hyperbole with the passions and passionate speech. More recently, hyperbole has become the object of research in several branches of linguistics, specifically Pragmatics including Relevance Theory (Carston & Wearing 2011, Norrick 2004, Cognitive Studies, especially regarding the interplay with metaphor and irony (Barnden 2017, Burgers, Brugman, Renardel de Lavalette & Steen 2016, Burgers, Renardel de Lavalette & Steen 2018, Colston & Keller 1998, Peña & Ruiz de Mendoza 2017 and political discourse studies (Kalkhoven & De Landtsheer 2016). They have emphasised the scalar and evaluative character of hyperbole and have noted its frequent usage in polemic and emotive discourse. Here we take a corpus-based view at the relationship of hyperbole and metaphor, specifically their combination in political discourse, both in the short term but also in a medium-term discoursehistorical perspective (Reisigl & Wodak 2009).
Based on a research corpus drawn from politicians' speeches and interviews and press texts dealing with Britain's withdrawal from the European Union ("Brexit") from 2016 to 2020, the paper investigates the role of hyperbolic metaphors. Our central example are hyperbolic applications of the proverb 'You cannot eat your cake and have it (too)', which together with further hyperbolic metaphors helped to heighten the emotional and polemical impact of the pro-Brexit argument. Whilst this effect may be deemed rhetorically successful in the short term (insofar as pro-Brexit-hyperbole facilitated victory in 2016 referendum and Johnson's electoral victory in 2019), its long-term effect on political discourse in Britain is ambivalent. Its boost for the emotionalisation of public discourse precipitated a general polarisation and radicalisation of the political public, which can also be witnessed in the debate about the COVID-19 pandemic.

Brexit, emotions and metaphor
Over the past five years, the public debates in the United Kingdom (UK) about Britain's withdrawal from the (EU), which was officially completed in January 2020 have been a prominent site for emotionalised political debates Britain (Buckledee 2018, Koller, Kopf & Miglbauer 2019, Charteris-Black 2019, Oliver 2018). An early climax of that debate was reached in June 2016 when, after about four months of intensive (and several years of preparatory) campaigning for Brexit by "Eurosceptics", a 51.9% majority of the UK electorate voted in favour of withdrawal. The most prominent emotions connected with the Eurosceptic motivation for Brexit were ANGER, e.g. about a perceived unfair financial and administrative burden on Britain imposed by the EU, FEAR, e.g. of growing mass immigration from other EU countries, and PRIDE, e.g. in Britain's national sovereignty and its history as an independent nation state (Rowinski 2017, Spiering 2015. During the referendum campaign, Brexit opponents expressed and propagated their emotions, too, e.g. FEAR of their nation losing allies in the EU and, with them, economic and political clout internationally, but they were beaten back by pro-Brexit voices who denounced such emotions as .being deliberately invented, e.g. through the dysphemistic label "Project Fear" (Payne 2016, Pesendorfer 2020. Metaphors have played a key role in expressing both the afore-mentioned basic emotions triggered by Brexit, as well as the more complex, mediated reactions during the different phases of the public debate as it unfolded between 2016 and 2020 (Charteris-Black 2019, Dallison 2017a, b, Đurović & Silaški 2018, Musolff 2017. This is no surprise as figurative language is a fundamental characteristic of political communication (Lakoff 1996, Lakoff & Johnson 1980/2003, Musolff 2016. But the frequency, intensity and complexity of Brexitmetaphorisations was so pervasive that it led to the emergence of a special "Metaphor Brexicon" (Charteris-Black 2019: 323) as part of the Brexit-jargon, many of whose terms and allusions are comprehensible only to insiders of the British media "community of practice" (Holmes & Meyerhoff 1999). Consider the following headlines: (1) Why shouldn't we try to have our Brexit cake and eat it too? ( Without further contextualisation, these headlines are enigmatic: at best, readers can make out that Brexit is viewed, strangely enough, as a "cake", that there is an ideology based on it ("cakeism", comparable to other "isms") and that a weird combination of "rosbif" (a supposed mock-European loan of English roast beef) with cake is associated with Boris Johnson, the British Prime Minister at the time of writing and the leading pro-Brexit-campaigner from February 2016 onwards. 1 If they have a good knowledge of English idioms they may recognise the allusion to the proverb, You cannot have your cake and eat it (too) in (1), 2 but its usage in that example is problematic because it asks a seemingly senseless question: if common sense -as embodied in the proverb -states that 'eating a cake' and also 'having it' (in the archaic sense of keeping it) is impossible and/ or unjustifiable, 3 why suggest that it is worth trying?
In the following section we focus on applications of this proverb as an example of how a combination of metaphor and hyperbole can trigger the intensification of emotional reactions and lead to a polarisation and radicalisation of public debate. The sample of applications of the have/eat cake proverb includes 208 instances of the phrase and amounts to 139,396 word tokens; it is drawn from print and online versions of Daily  3 The Daily Telegraph, for instance, usually applies the proverb in its standard version, e.g. in a headline from 2014, "The whining rich can't have their cake and eat it", which denounced as hypocritical the attitude of those who "monopolise wealth in the 21st Century [and still] moan about taxes" (The Daily Telegraph, 11/08/2014).

Guardian/Observer, The Independent, The National, The New European, The Scotsman, The Spectator, The Street, The Sun, The Times/Sunday Times, The Yorkshire Post. 4 we first give an overview of the "discourse career" of the cake-Brexit metaphor and subsequently analyse its emotionalisation effect before contextualising it later on in the wider perspective of Brexit-hyperbole.

Proverb and hyperbole
The application of a special version of the proverb, You cannot have your cake and eat it, to Brexit by Boris Johnson was originally a self-quotation. Back in 2009, i.e. long before Brexit but when he was already the Mayor of London, Johnson characterised his political ambitions by way of a metaphor that alluded to the well-known proverb in an interview: (5) "Let's not beat about the bush here. My policy on cake is still pro having it and pro eating it." (The Daily Telegraph, 10/04/2009) Johnson's interview answer can be interpreted as a (mildly) self-ironical confirmation that his political ambitions were extremely high but their achievability was uncertain. 5 In order to avoid being seen as over-ambitious, he played with the standard 'impossibility/ absurdity' sense of the proverb but also indicated a determination to 'try the impossible'. It had a hyperbolic element that added a humorous aspect and ambiguity: 6 strictly speaking, having/keeping a cake and eating the same cake is impossible. Thus, Johnson presented a goal that he intended to as an 'impossibility' -while it was not absolutely impossible after all to achieve (as we know with hindsight, given his rise to power as the UK's Prime Minister within a decade). This internal contradiction makes his statement quasiparadoxical: Johnson used the extreme end of the scale of ambition as a benchmark instead of the more plausible but less exciting notion of achieving a specific, limited goal (which would have equalled eating the cake but not keeping it). His formulation fulfilled the basic condition of hyperbolic language use as "an expression that is more extreme than justified given its ontological referent" (Burgers, Brugman, Renardel de Lavalette & Steen 2016: 166). Its "extreme" aspect lay in the degree of qualitative exaggeration, which is one of the main types of hyperbole: something that is in fact not viewed by the speaker as being completely unachievable is presented as if it were (Colston & O'Brien 2000, Norrick 2004).
Seven years later Johnson applied this proverb version to announce his Brexitambitions in as positive a light as possible to the right-wing tabloid The Sun. By this time, he had become Foreign Secretary in the Conservative government under Prime Minister Theresa May, which had emerged after the 2016 Brexit-referendum: (6) 'We'll have our cake and eat it'. BORIS Johnson has declared his support for a hard Brexit […]. He also insisted we will get immigration controls back as well as continuing open trade with the EU. Mr Johnson told The Sun: "Our policy is having our cake and eating it. We are Pro-secco but by no means anti-pasto". (The Sun, 30/09/2016) The pun on Italian culinary products in the last sentence showed that Johnson still tried to appear witty and jovial, but his proverb-application was no longer meant as an ironic "echo" (Wilson & Sperber 2012) of the standard (negated) proverb, but rather as an emphatic (non-standard) assertion applied to UK policy towards the EU. Johnson's policy promise of having the cake and eating it openly announced that the UK government tried to achieve two objectives that were often seen as excluding each other, i.e. maintaining on the one hand full "immigration controls" and on the other hand "open trade". The EU's "internal market" system, however, implied that the free movement of people (i.e. migration from one EU country to another) and free trade were interdependent; Johnson's aim of keeping freedom of trade for the UK whilst ditching freedom of movement was therefore an implicit challenge to the EU's regulations. Unlike his 2009 usage, Johnson's announcement of combining both goals was intended to be received as a reassuring promise that the British government would try to achieve maximum benefits from Brexit. Emotionally, it could be linked to FEAR (or at least UNEASE) that the final Brexit outcome might turn out to be disadvantageous but also to national PRIDE in Britain being strong enough to negotiate a favourable deal. The promise aimed, unsurprisingly, at reinforcing the Brexit-supporters' feelings of optimism.
This interpretation seems to me more likely than the reading of it as a defensive argument in a "moral dilemma" (Charteris-Black 2019: 3). Brexit -with its onesided ambitions for a maximum, 'win-win' outcome for the British side may have been a moral dilemma for its opponents but these were not at all Johnson's (or the Sun's) chief addressees. Johnson's statement in example (6) is a proud, triumphant announcement of following up the promises made before the referendum until a full victory can be declared. Its hyperbole is not tinged by irony; instead, it pronounces the achievability of the impossible as a viable policy and tops it up with jokey wordplay. Of course Johnson was aware of the Brexit-opponents and other critics' derision for his optimism about Britain having its cake and eating it. Such critics could be found across the whole range of media. Thus, the left-wing Guardian and the liberal Economist, but also the pro-conservative Spectator and even the fervently pro-Brexit Daily Express admonished him:  (7) and (8) invoke the standard proverb version as the commonsense position (from their standpoint) against Johnson's folly. (9) suggests that if the UK takes an egotistic stance, so will probably "others", i.e. the EU as a whole and/or its various member states. (10) on the other hand insinuates that the others will "gang up" on Britain to not allow its having and eating the Brexit-cake. In (10) Johnson's policy is implicitly endorsed in principle but still viewed as doomed because of the intransigence of the EU as the opposing party. Notwithstanding the varying stances taken in these reactions, all of them demonstrate that by the summer/autumn of 2016 Johnson's can have and eat cake proverb version had already acquired catchphrase status, allowing journalists to use it as an allusion (e.g. "Other people want cake too") on the assumption that their readers were sufficiently familiar with it to recognise its "echo" in ironical references and contradictions. Its popularity even spread to the EU where the then president of the European Council, Donald Tusk, engaged in an elaborate dismissal of what he dubbed Johnson's "cake philosophy": (11) "The brutal truth is that Brexit will be a loss for all of us, […] There will be no cakes on the table for anyone. There will be only salt and vinegar." (quoted in The Independent, 13/10/2016) But whilst Johnson's critics from various quarters took pot shots at his proverb use, his allies in the now Brexit-pursuing government copied his recipe for hyperbolic metaphor. The strongly Brexit-enthusiastic International Trade Secretary Liam Fox was quoted with the prediction that Britain would become Another ally, the new secretary of state appointed for leading the negotiations with the EU, David Davis, bragged that the (13) "negotiating cards with the EU [were] incredibly stacked in our way." (quoted in The Guardian, 12/10/2016) In November 2016, Johnson's proverb version was even given an accidental but quasi-official endorsement by May's Cabinet when a Conservative party aide, Julia Dockerill, was photographed carrying notes into the Prime Minister's Office which indicated that the government's Brexit preparations were based on Johnson's slogan. It read: "'What's the model? Have cake and eat it'" (Daily Mirror, 29/11/2016). Ignoring several dementis by government spokespersons, the British press almost unanimously interpreted the notes as representing the gist of the government's strategy (Musolff 2019: 211-212). The phrase was now also associated with the Prime Minister Theresa May, who was, for instance, reported as "still telling Britons they [could] have their cake and eat it" by "promising barrier-free access to the single market while stopping EU migrants" (The Economist, 01/04/2017).
However, after a national election in June 2017 that deprived the Conservatives of an outright majority in parliament, and with increasing experience of harderthan-expected negotiations with the EU, the government's ostentatious optimism as expressed in Johnson's eat and have cake promise began to weaken. Several newspapers reported that May was recognizing the unfeasibility of retaining all benefits of EU membership without incurring any losses. This change motivated headlines such as, The asserted version of the proverb was now increasingly linked to the goal of a so-called "hard" Brexit that would sever most economic and administrative ties with the EU and incur substantial economic risks. Finance experts in particular, e.g. the Chancellor of the Exchequer, Philipp Hammond, and the Governor of the Bank of England, Mark Carney, urged caution about such a prospect by "discourag[ing] talk of cake" (Hammond, quoted in Daily Mail, 27/06/2017) and denouncing as an illusion the thought that Brexit would be "a gentle stroll or smooth path to a land of cake and consumption" (Carney, quoted in Daily Mail, 20/062017).
However, if Carney and Hammond had intended to bury Johnson's slogan by mocking it, they had not reckoned with the Labour-party under Jeremy Corbyn adopting it in a belated attempt to join in and gain from maximalist Brexit rhetoric. Rebecca Long-Bailey, Labour's shadow business secretary, claimed it for her party: (16) "We want to have our cake and eat it, as do most parties in Westminster" (quoted in The Guardian, 16/07/2017).
Her statement was, predictably, seized upon as revealing a hypocritical stance of officially opposing the Conservative-led Brexit whilst surreptitiously supporting it for Labour-specific purposes. The Liberal Democrats' spokesman, Tom Brake, commented that Labour's Brexit position was "so indistinguishable from the Conservatives that they have started parroting Boris Johnson" (The Independent, 16 July 2017), and the magazine The Spectator portrayed Long-Bailey ironically as "channel[ing] her inner Boris Johnson" (The Spectator, 16 July 2017). Following the interview, the cake-phrase became a focus for Labour-internal disputes. When their Shadow Chancellor, John McDonnell, suggested that after a change in government Labour would abide by the referendum result but ensure tariff-free access to the single market and the customs union, he was accused by the former Labour Prime Minister and Brexit-opponent Tony Blair of caving in to the Conservatives' "having cake and eating it" strategy (The Guardian, 27/11/2017, The New European, 11/12/2017, The Daily Telegraph, 04/01/2018. With both the largest government and opposition parties each claiming the 'eat-and-have cake' stance for themselves but also disputing it among themselves, the slogan became an easy target for allusive parody by politicians and media commentators who competed to coin new rhetorical niches for themselves to gain the public's attention. Some of the more colourful examples included a warning by Sir Martin Donnelly, a Brexit-critical former civil servant, that leaving the European customs union would be The polemical, sarcastic and satirizing drift of these uses, including use of taboo words, bears the hallmarks of hyperbole. Analytically, we can distinguish between two levels of a) proverb-application (in the sense of a propositionally elaborated or allusive use of the can(not) have and eat cake situation and b) its further pragmatic exploitation -through hyperbole -to achieve additional polemical and argumentative, also humorous effects. The new proverb version became a clichéd "scenario" (Musolff 2006) with stereotypical participants (CAKE, EATER), event structure (EATING AND KEEPING) and default evaluative bias ((IM)POSSIBILITY) that served as a 'ground' for rhetorical-pragmatic 'figure'/Gestalt-effects. It is 'mentioned' or echoed rather than 'used' (Sperber & Wilson 1981), both in the satirical sketches quoted above (see examples 17-19) as well as in the laconic allusions cited earlier in section 2 (see examples 1-4).

Proverb-free hyperbole
In our sample of overall 208 articles over five years, applications of the Brexitrelated cake-phrase rise from 31 instances in 2016 to 85 instances in 2018 and then fall to under 20 instances in 2020. The decline may be due to a combination of factors, i.e. the media reaching a 'saturation point' in satirizing the slogan, a realization even on the part of Brexiters that the maximalist negotiation stance become obsolete in view of a hardening EU negotiation tactic. Johnson, as Brexit's (and the cake slogan's) chief propagator in public discourse, withdrew from Theresa May's cabinet in June 2018 on account of their disagreement on Brexit strategy, which triggered a Conservative inner-party conflict that led in the end to May's resignation and replacement by Johnson (in July 2019). But whilst the allusions to the eat and have cake proverb became fewer and fewer in public discourse, the hyperbole did not, and certainly not in Johnson's rhetoric. Free to write his column in the Daily Telegraph without having to obey Cabinet discipline, he denounced May's strategy and deal in the starkest terms, no longer invoking a funny proverb version but instead relying on a sinister WAR scenario of 'complete victory or total defeat/ surrender with ensuing enslavement' as the conceptual frame for Brexit: In these examples, a stark opposition is drawn between the 'good' side of (pro-) Brexit Britain and 'evil' forces including both the EU and May's government trying to vanquish, take captive and enslave their victim. 7 The basic Brexit-related emotions had remained the same since the time of the pro-Brexit campaign: FEAR, ANGER, and (hurt) national PRIDE. However, by spring 2019 they had been rhetorically 'escalated' to an extreme degree and could hardly be topped. In order to keep up his Brexit promise, Johnson had to switch to further extreme rhetorical moves. One of these was to promise a kind of epiphany of a 'maximum gain' Brexit appearing miraculously over the horizon: (26) So don't despair. Don't give up. [Brexit] is going to happen, and at that wonderful moment it will be as though the lights have come on at some raucous party; or as if a turbulent sea has withdrawn to expose the creatures of the shore.... (The Daily Telegraph, 15/04/2019) In a complementary move he threatened the EU with a violent angry reaction by a Britain likened to the Comic strip figure "Incredible Hulk": Both the renewed 'Brexit-as-paradise' promise and the threat of acting like the "Hulk" were still in line with the hyperbolic scenarios used during the whole Brexit referendum campaign: the win-win vision of a maximum gain through Brexit and its depiction as the only alternative to complete surrender and defeat. However, when "Brexit day" actually came on 31 January 2020 (after several delays), its economic and political impact was nearly zero. Apart from small festivities of Conservative Brexiters in or near their party headquarters there were few emotional reactions and even the Daily Telegraph mainly highlighted the achievement of having passed "three years of bust-ups, backstabbing, tears and turmoil" that had made "the mere act [sic!] of departure" so difficult (The Daily Telegraph 31/01/2020). If the day of Britain officially leaving the EU was a "mere act of departure" even in the eyes of Johnson's most sympathetic media outlet, it certainly was nowhere near a "total victory" or the "wonderful moment" when "lights coming on at a raucous party". On the other hand, it was not a complete defeat or catastrophe for the UK either. So, was Johnson's hyberbolic rhetoric just "much ado about nothing", a mere accompaniment to the political process that had no effect on its outcome?

Preliminary conclusions
Obviously, the long-term effects of Brexit, their evaluation as success or failure, and their emotional effect are not known yet. There have been voices, mainly on the part of Brexit-opponents, which maintain that the emotionalised rhetoric of the Brexit disputes has led to a deterioration of debating culture and a radicalisation of the public sphere in the United Kingdom (The Guardian, 12/10/2019: "Brexiters' adoption of war language will stop Britain from finding peace", The Observer, 29/09/2019: "Boris Johnson seeks to divide and conquer with his incendiary rhetoric"). Johnson's use of figurative speech is highly deliberate and crafted (Margulies 2019), not a chance product of a specific situation. The coinage of a non-standard version of a proverb, whose canonical form has been entrenched in everyday discourse for four centuries, and the colourful ornamentation of the UK-EU conflict as a battle of a single nation against the threat of enslavement by a contemptuous enemy, evidenced in the examples cited above show that Johnson purposefully presented Brexit as a contest between good and bad, at the end of which could only stand victory or total defeat. The psycho-political intention behind this strategy is easy to discern: by portraying Brexit in the most extreme contrasting evaluations, Johnson and his allies tried to raise and mobilise the emotions of their followers to a maximum. The outcomes of the 2016 Brexit referendum with its majority in favour of Brexit, and of the national election in December 2019, which gave Johnson a huge parliamentary majority (365 out of 650 seats and a 43.6% of the vote) seem to vindicate this strategy at least in terms of electoral success. In terms of political strategy, the use of hyperbolic figurative language apparently boosts and 'escalates' the emotional appeal and impact of specific policies, i.e. their connection with positive emotions such as PRIDE and a need to avoid or overcome negative ones (FEAR, ANGER). Acceptance of that connection by recipients in turn boosts voter support for and readiness to actively endorse those policies.
Thus, whilst evidently fit for the purpose of emotionalisation in the short-term, the cake-and liberation war scenarios suffer from an inherent problem that originates in what one might call 'hyperbolic overload'. It is not so much an issue that they are unrealistic and resemble fairy tale and/or comic-story plots but rather that the hyperbolic suggestion of an extremely positive outcome loses its pragmatic value over time and demands an ever more hyperbolic escalation. Like other openly evaluative semantic and pragmatic effects, e.g. euphemism, it is susceptible to a 'treadmill' effect over time (Allen & Burridge 1991, Pinker 1994, Crespo-Fernández 2006. The more often and the more emphatically they are used, the less convincing they become. This deterioration seems to be reinforced by an inbuilt comparison of the 'super-positive' intended meaning with perceived 'reality'. The supposed 'positive' politeness of euphemisms such as African American instead of Black American or of passing away instead of dying loses its appeal if experiences of continuing racial discrimination as a social evil or of death as a fearful event expose it as phoney. In the case of hyperbole, which has no intrinsic polarity, it is the exaggeration 'value' itself that diminishes in view of the experiential contrast. If the maximum gain or total victory promised in the pro-Brexit scenarios remains elusive, the suggested extreme result will not come true. The hyperbolic promise becomes a 'hostage to fortune', which is extremely risky in politics, given its unpredictability. However, it is unlikely Johnson himself will refrain from hyperbolic metaphor use -it seems embedded in his rhetoric. When Britain, like the rest of the world, was facing a new challenge shortly after the low-key event of official Brexit day (31 January 2020), i.e. the outbreak of the COVID-19 pandemic, his pragmaticrhetorical choice was again in favour of optimistic hyperbole in the guise of metaphorical idioms: (28) "We already have a fantastic NHS, fantastic testing systems and fantastic surveillance of the spread of the disease … I want to stress that for the vast majority of the people of this country, we should be going about our business as usual." (quoted in The Guardian, 23/03/2020) (29) " [...] looking at it all, that we can turn the tide within the next 12 weeks, and I'm absolutely confident that we can send coronavirus packing in this country." (quoted in The Guardian, 23/03/2020) (30) "We have growing confidence that we will have a test, track and trace operation that will be world-beating and yes, it will be in place by June 1." (quoted in The Guardian, 20/05/2020).
Whilst "fantastic" in (28) may pass as fair, if strong praise, its three-time repetition points in the direction of hyperbole. Turn the tide and send packing in (29) are idiomatic phrases (Ayto 2010: 254, Shorter Oxford English Dictionary 1993, vol. 2: 2066) that set up a confrontation scenario (UK vs. Coronavirus) with implies superiority (and hence, likely victory) for one side over the other. In (30), the claim to have a world-beating "track and trace" system for people who were infected by the COVID-19 virus in 12 days' time (20 May -1 June) as part of an inherently competitive scenario of the UK beating the whole world in the field of technology-driven pandemic management was as over-ambitious as Johnson's Brexit promises. Predictably, its trustworthiness was challenged, not just by the political opposition but even by conservative-leaning media, as the experience of its at best limited success made it an easy target for criticism. 8 Johnson tried to deflect such criticism by accusing his opponents of casting aspersions on the National Health Service and reiterated his world-beating boast (Daily Mail, 03/06/2020, 06/08/2020), perhaps operating on the assumption that the advantage of employing hyperbolic figurative language as a means to present optimistic messages outweighs the cost of incurring accusations of insincerity. The general appeal of hyperbole for politicians and journalists may lie in its multifunctionality, i.e. the fact that it triggers, answers and escalates multiple basic emotions, e.g. by expressing PRIDE, reassuring FEAR and even seemingly justifying ANGER. As such it seems the trope of choice for achieving political emotionalisation.
