Comment: what happens when US presidents enter British elections Published on: 4 December 2019 Writing for The Conversation, Martin Farr discusses the history of the special relationship between the UK and US, and the timing of President Trump's latest visit to the UK. , Foreign affairs rarely play a role in British elections. The exception, of course, is Europe: both Labour in and the Conservatives in won a narrow parliamentary majority after promising a referendum on UK membership. For reasons of practicality and protocol, elections are usually scheduled to avoid summits, or the visits of foreign leaders. But nothing is normal any more and 2019鈥檚 rushed general election features the first visit of a US president to Watford, an unprepossessing commuter town north of London. Donald Trump flew into the UK on December 2 for a two-day visit to attend a meeting of NATO leaders marking the 70th anniversary of the alliance. One of the many curiosities of our age is that this most US president for the British should come so . Another is that Boris Johnson, a US-born, Atlanticist prime minister, earnestly the leader of the free world was not in the UK. At the same time, Jeremy Corbyn, a very-far-from Atlanticist leader of the opposition, is that he should be. Using the special relationship The Foreign Office may be the second most prestigious office of state, but in elections, foreign secretaries or their shadows from the opposition seldom find themselves much called on. Defence has had an impact though, such as in and when Labour was portrayed as too pacifistic, and in , when the party wished they had been so. Those episodes revolved around the between the US and UK 鈥 and prime ministers have not been averse to the blandishments of presidents on pre-election visits to the US, such as Harold Macmillan in , and David Cameron in . Presidents have been prepared to assist in other ways, as I鈥檝e been examining in my research on the historical relationships . Ronald Reagan鈥檚 humiliation of Labour leader Neil Kinnock in calculatedly bolstered the then prime minister Margaret Thatcher. But there has never been a presidential visit during a general election before now. Part of the appeal of the Leave campaign in the EU referendum was Britain going out into the world and making more of its historic ties with what Winston Churchill called 鈥溾. This overlooked the fact that every American president since Dwight Eisenhower in the 1950s has because it enhanced US interests to have its closest ally at the centre of what became the world鈥檚 largest trading bloc. The exception, as ever, is President Trump. The special relationship has weakened in the topsy-turvy political world since 2015 鈥 the year Corbyn became Labour leader, Trump announced his presidential candidacy and the British parliament passed to hold a referendum on EU membership. In April Barack Obama 鈥 the recent American president for the British public 鈥 visited the UK at the invitation of the prime minister, David Cameron, to assist with the increasingly panicked Remain campaign. At the , Obama told the world that in the event of Brexit, Britain would be at 鈥渢he back of the queue鈥 for a trade deal. His intervention backfired, the Leave narrative of a remote and condescending elite 鈥 and Remain never recovered. Always keen to present himself in opposition to Obama, Trump has pushed his own anti-establishment narrative, which extended to condemnation of transnational institutions including NATO and the EU. In offering the promise of a free trade agreement to the UK, Trump has presented himself as a champion of self-government and so of Brexit, responsibility for which he characteristically . As if that were not a sufficient transgression of diplomatic norms, Trump also in 2016 that Brexit Party leader, Nigel Farage, should be appointed British ambassador to the US. More seriously, his relationship with Johnson鈥檚 predecessor, Theresa May, was quite unlike that of any other president and prime minister, as I鈥檝e examined in forthcoming research. Standing alongside May in and , Trump embarrassed her, and breaking with any sense of protocol or propriety, also praised the person clearly positioning himself to replace her 鈥 who, shortly thereafter, did just that. US presidents have attended NATO summits in the UK before 鈥 Jimmy Carter in , George HW Bush in , and Obama in . But Trump鈥檚 attitudes towards NATO were originally of British consternation at his election. It wasn鈥檛 known then that he wasn鈥檛 a man of settled policies. In three years he has moved from being NATO鈥檚 most prominent , to its staunchest in the face of criticism of the . A liability for Johnson It would never have been necessary with any other president, but on this December visit Trump has done as requested 鈥 he has and said he would 鈥渟tay out of the election鈥. Except that, insofar as he flagrantly something he said the last time he was in the UK in the express interest of the prime minister, stayed out of British politics. Significantly, the impact of Trump鈥檚 visit to the UK is on a domestic policy area that is, by contrast, always central to elections: the National Health Service. In a on all sides by millions of this, billions of that, and trillions of the other, Labour has persistently claimed there will be a US-imposed increase in the NHS drugs bill of . NHS staff the now-traditional public protests that mark a Trump visit. If Trump was ever an asset for Johnson, he鈥檚 now deemed a liability. The president sees something of himself in man he鈥檚 called 鈥溾, not least perhaps their at times disarming . But given British public attitudes to Trump, it鈥檚 prudent for Johnson to maintain during the last week of a tight election. Trump鈥檚 toxicity has the potential to poison Johnson鈥檚 hitherto effective campaign. So after much speculation as to whether they would meet 鈥 itself extraordinary 鈥 Johnson and Trump , but, equally extraordinarily, there were of the host and his guest at that meeting at Number 10 or at a Buckingham Palace reception. The two were eventually photographed together arriving at The Grove, the venue for the NATO leaders summit in Watford. By contrast, Corbyn has wanted nothing more than the chance to be photographed 鈥 though it emerged they did not meet at the palace. But not on NATO. On which they agree. A voter could be forgiven for being confused. , Senior Lecturer in Modern and Contemporary British History, This article is republished from under a Creative Commons license. Read the .
