This kind of establishment revolt is what you call a capital strike …
I don't know if anyone else on here has checked the three part Al-Jazeera documentary on Labour that's just come out.
It's extremely biased, but it's also hard to answer for Labour, I think, pretty much an assembly of all the most compelling proofs that the "antisemitism crisis" was, apart from the fact that real antisemitism within UK Labour does exist, a fit-up, distortion and exaggeration for factional purposes designed to destroy Corbyn's movement and restore control to the Labour right.
There's also ample evidence of shocking racism in there, from the systematic suspension of Jewish members, to the treatment of the Muslim-majority CLP in Newham more recently.
It's all a bit of a shame, because with the Tories this godawful and Brexit in the rear view, I reckon Corbyn would've stood a chance at election!
