Three more figures were this week suspended from Labour over allegations of antisemitism. The party acted against Bradford's former Lord Mayor Khadim Hussain, and activists Bob Campbell and Scott Nelson .

Mr Hussain posted a comment on social media which implied Israel was secretly arming terrorist group Daesh. He also promoted a post on Facebook that said Hitler killed "six million Zionists". He did not deny posting the messages, but said, "under no circumstances I am antisemitic."

A Labour spokeswoman confirmed he had been suspended pending an investigation.

Activist Mr Nelson was suspended by the party last year after he posted a series of tweets about "Jewish blood" behind companies including Tesco and Marks and Spencer.

But it emerged on Wednesday that the Essex-based activist had been told he could be re-admitted to the party in 2018.

A letter sent to Mr Nelson, which was obtained by political site Guido Fawkes, confirmed that the party's national executive committee would consider an application to re-join after two years.

Middlesbrough Momentum activist Mr Campbell was suspended pending investigation, following statements he made on Facebook suggesting that Mossad was behind Daesh. He denied he was antisemitic.

A total of six Labour members have been suspended over allegations of antisemitism in recent weeks.
