Following the referendum on the United Kingdom's membership of the European Union resulting in a win for the leave or 'Brexit' campaign in June 2016, McEwan wrote a critical opinion article for The Guardian newspaper titled "Britain is changed utterly. Unless this summer is just a bad dream", published 9 July 2016. In the article, McEwan attempted to make sense of the aftermath and consequences of the 'Brexit' vote, noting: " Everything is changed utterly. Or about to be, as soon as your new leader is chosen. The country you live in, the parliamentary democracy that ruled it, for good or bad, has been trumped by a plebiscite of dubious purpose and unacknowledged status. From our agriculture to our science and our universities, from our law to our international relations to our commerce and trade and politics, and who and what we are in the world – all is up for a curious, unequal renegotiation with our European neighbours." McEwan's piece appeared to conclude with a sense of bewilderment and unease at how events were panning out, anticipating the ascension of Theresa May to the leadership of the Conservative Party and her appointment as Prime Minister, and noting how the previously unthinkable in British politics had actually happened. (McEwan's article was published on 9 July, and May effectively won the Conservative Party leadership contest on 11 July, which precipitated her appointment as Prime Minister two days later). In May 2017, speaking at a London conference on Brexit, apparently referring to what he believed to be the older demographic of leave voters, McEwan stated that 'one and a half million oldsters freshly in their graves' would result in a putative second referendum returning a 'remain' outcome.
