I've never thought he would stick around. Like someone was quoted saying, he wanted to BE prime minister, and he wants to HAVE BEEN prime minister, but the hard bit in the middle? Not so much.
Especially given that he's going to be the PM of Brexit and Covid and fucking Barnard Castle, not the good time PM he always imagined himself as.
He's largely an incompetent lazy sociopath and I'd like to see him gone very very soon. Unfortunately he'd be replaced by Gove no doubt, who is a terrifyingly grim and reptilian prospect.
