David Cameron drafted alternative speeches as he awaited the result of last year's fateful and too-close-to-call referendum. Outside 10 Downing Street on the morning following the narrow rejection of EU membership, he chose Document No 2. It said, more or less, "Oops, sorry, I'm out of here".
There followed an extraordinary Tory party leadership contest in which the various candidates shot one another, or themselves, on live TV, with the exception of Theresa May, who prevailed either on merit or because her gun jammed.
Mrs May campaigned on the Remain side and has presided over a government which has chosen the most damaging possible interpretation of the referendum's thin Leave majority, risking a comprehensive rupture with Britain's natural trading partners and political allies in Europe.
