Political commentator Chris Deerin:

By the time Corbyn is finished, Labour will only be fit for conspiracy theorists and Jew-baiters

I find it all genuinely heartbreaking. It's awful to watch some of the party's brightest talents quit politics in despair or disillusionment. It's infuriating that a bunch of ideological obsessives from the bottom of the barrel are blithely destroying one of the UK's two great vehicles for social change. And the very idea it could be allowed to continue after June is enraging.

So for me, and I hope for you, this is an ABL election – Anyone But Labour. The only hope I can locate is that the humiliation about to be visited on the party is so complete, so shockingly great, so unprecedentedly painful, that not even the most shameless Trot could credibly consider carrying on. Let's show these hideous goons there is no floor to our contempt. Let's show them who's boss.
