I don’t know if Boris Johnson is as surprised to be prime minister as those who’ve known him for 20 years, and worked for him when he was Spectator editor, and became incredibly grumpy at his seeming pathological inability to make up his mind.

But it all felt a bit unreal and disconcerting to see Johnson at the dispatch box today in the Commons – even though I’ve been calling him a shoo-in for the job for months.
