There is no chance that Corbyn will be allowed to run again under the Labour Party banner. Starmer is blocking anyone who wants change that goes beyond tweaks. Corbyn says he will run for reelection; perhaps he will have to run as an independent.

Given Starmer's plutocratist policies and dirty tricks for imposing them on the party, it is clear he will not allow Momentum or anyone else who wants more leftist policies to have any influence. If I were British, and if Corbyn had inspired me to join Labour, I would quit and support something else.

Could Corbyn join the Green Party and perhaps run as a Green candidate?
