Jeremy Corbyn's Brexit policy, at least, will be Theresa May's by the end of the week. If she wants to save her job. From her own party, which, being mostly Southern, is mostly Remain.
No one votes based on this issue, anyway. Did the Lib Dems get 48 per cent of the vote? Well, there you are, then. Nor will there be any renaissance of UKIP.
UKIP has always been made up of, and addressed to, the wrong people. The ones who think that in 1975 they "voted for a free trade area". Or, as it was and is otherwise known, the Customs Union.
