"You put your right leg in, you take your right leg out..." so the Boris Johnson hokey cokey continues, as arbitrary as ever. First he's proposing a toast to Theresa May, celebrating the chequers deal that they all agree on. and no, he won't be resigning. but hang on a minute. David Davis is resigning. (Only because he's Brexit minister, and he can't conscientiously implement this. He's not criticising May, or objecting to the agreement). So suddenly Johnson looks as if he's missed and opportunity, so he discovers a deep conscientious objection - "can't sing this song with conviction" and resigns.
And what a palaver he makes of it. He simply fails to turn up at a Foreign Office functions he's supposed to be chairing - no explanation, no apology. He's sat at home composing his letter of resignation in splendid isolation - unless you count the pet photographer who's been invited to record this Churchillian occasion. You couldn't make it up.
It's an entirely predictable climax to the erratic, vain procession which has been Johnon's career over the last three years. What makes it chilling is that apparently this immediately takes him to the favourite position in the betting about who succeeds May. OK, so Trump and Rees-Mogg both think Johnson is Prime Minister material. Who else could possible agree with them? which MPs seriously look forward to the prospect of sitting in the House of commons with this charlatan as their leader?
