Basically he's someone who would never, ever have been PM if it hadn't been in those very specific circumstances: Boris had to go, and they tried Truss but it was a disaster. So they had to give him a shot at it by default. In normal political times it would never have been Sunak. Or Truss. Or May. Boris was always going to have his day, but really since Cameron fled that podium whistling that little tune, it's all been a hilarious mess.
