Unless the Grey report means he absolutely has to go, I’m not convinced a vote of no confidence would pass, which as others have said, would probably be more damaging than him going.
If he does go, Labour need to push on these other allegations as not BoJo but ingrained in Tory culture.
Two years may be a long time in politics but the next year will not be kind to whoever is in charge.
Random thought for next leader f BoJo goes: Kwarteng seems to be being quite critical of govt for a minister – very outside chance of going for it?
