Labour activist suspended amid antisemitism allegations boasts about voting for Pete Willsman

But last week he reacted furiously to the announcement that the Momentum group were withdrawing their support for one of the so-called #JC9 slate of NEC election candidates in response to the JC's exposure of Mr Willsman's comments about Jewish "Trump fanatics".

In a Twitter post, Mr Watson responded: "Too late. I've already voted for the #JC9. And I don't regret it. #StandwithCorbyn."

On Sunday, one senior Labour figure said they feared "numerous" Labour members suspended by the party, often for hardcore antisemitic activity, had received ballot papers allowing them to vote in the NEC and National Policy Forum elections.

"This is the consequence of Labour's failure to deal properly and quickly and indeed fairly with the massive backlog of incidents of alleged antisemitic conduct.

"After his comments about "rabbis" and Jewish people in general, Pete Willsman will almost undoubtedly be the go-to candidate."

The JC first revealed Mr Willsman's remarks on the day of the NEC meeting that approved the party's new code of conduct on July 17.

But only after we released audio of his already reported comments last Monday did several left-wing figures - including commentator Owen Jones - openly criticise him.

A Labour spokesperson refused to comment on Mr Watson's claim that he had voted for Mr Willsman in the NEC election saying the Party "do not comment on individuals who are suspended."
