So what now for Boris? He’s got to go through the selection process for a constituency, which he hasn’t yet settled upon, although I’ve outlined some of the options that might work for this week’s magazine. The favourite is Uxbridge; but his camp today are adamant that other seats are in play. One source tells me: ‘He is not expecting to get any special treatment at all, and he is prepared to go through the selection process like any other candidate.’

But the important thing for Boris is that he’s answered the big question before the Scottish independence referendum and party conference season, which were the two deadlines his secret campaign team had set for him. Move too close to 18 September and he’d look self-obsessed.
