Attack Boris all you like,” a recent headline claimed, “but he’s the only man who can save us from prime minister Corbyn”. I started to think about this, and Jeremy Hunt’s counter-claim that he was the only man who could stop Corbyn. And the more I thought about it, the more absurd it began to seem. It was like having a vote about who could best preserve us from man-eating guinea pigs.

It’s apparent as soon as you speak to any Labour figure who is not demented, or as you parse the writings and quarrels of the Corbynite media commentators, that they know that the Corbyn moment is over. The evidence, after all, is hard to refute, even if in-fighting Tories seem oblivious to it.
