In a better world, Labour’s leader would whip all of his caucus to reject the rotting corpse. In this world, we have a delusional and power-hungry old man lost in nostalgia for a go-it-alone People’s Republic of Great Britain of the 1970s that never was.
Sadly, the UK is stuck with him as opposition leader until this is resolved. The last thing that’s needed is an intra-party fight now that the clock is ticking again. After that, one way or another, the party needs to kick his bony arse to the kerb and give whomever in the party called loudest for a second referendum his spot.
