Ken Livingstone resigned from the Labour Party on 21 May. Good riddance!
He ceased to be a real left-winger decades ago, he has a clear record of high-profile antisemitic comments, and he has been aggressively persistent about them.
Yet the Labour Party is still blundering along without any open and thorough discussion of antisemitism. There are still people on the left who see nothing wrong in what Livingstone has said. Suspensions, expulsions, resignations will resolve little until we have that discussion.
