From Starmer's Statement;
And if – after all the pain, all the grief, and all the evidence in this report, there are still those who think there’s no problem with anti-semitism in the Labour Party. That it’s all exaggerated, or a factional attack.
Then, frankly, you are part of the problem too. And you should be nowhere near the Labour Party either.
Corbyn:
the scale of the problem was also dramatically overstated for political reasons by our opponents inside and outside the party, as well as by much of the media.
As I understand it, this is what he wouldn't retract and what he was suspended for.
It seems clear to me. Perhaps someone can convince me otherwise?
