It’s a version of the journey that most occupants of Downing Street make, slowly discarding the garb that got them there. In the next 10 days Johnson has to make two further steps along that road, and neither will be easy for him. The first is breaking with his former parliamentary supporters in the vote today on the new Covid tiering system. The Prime Minister is not new to parliamentary rebellions. As a backbencher last year, he led some of the largest in our history against his predecessor to bring her down. As a new premier he ruthlessly purged other backbenchers who made the mistake of thinking they could follow his example with the same impunity he had enjoyed. This will, however, be the first major rebellion since his election victory and this time the rebels look suspiciously like the gang that got him into office: a motley crue of ERG trouble makers, local populists, and ex-ministers hoping for a change in the weather. If there were ever a faction of Johnsonites, this was them. That’s presumably why there’s no talk of whips being withdrawn or sanctions imposed, although any newcomer who joins them in the voting lobby won’t be getting a job anytime soon.
