Boris Johnson has hit bottom. I really think there is nothing more despicable and dishonourable that he could have done than his article on today's Telegraph. Knowing perfectly well that the Brexit he howls for is both impossible and largely not defined at all, he covers his own party leader with insults for not achieving it. He is appealing to the most stupid, deviant, grotesque part of the Brexiteer crowd, to those to whom real life is far less important than their self-pleasing fictions and diseased fantasies. Here, ladies and gentlemen, is the demagogue in his full and shameless shape, such as Britain has not seen in living memory. He makes Trump sound like an honourable man, and I mean it.
