When I was asked to write this article I intended to start by saying that Nigel Farage had to choose whether he preferred that Britain should leave the EU or that he should remain Ukip’s leader, because the two were incompatible. I hope I was wrong about that, but there is some truth in it, and Nigel stated his own view a couple of months ago.
