Labour MP Neil Coyle has called on Jeremy Corbyn to “stick to his word” on tackling antisemitism after Chris Williamson was readmitted to the party.
He is one of 90 Labour MPs and peers who signed a letter demanding Mr Corbyn withdraw the whip from Mr Williamson.
Mr Williamson was suspended in February after he claimed the party had been “too apologetic” in response to criticism over its handling of antisemitism allegations.
Mr Coyle told talkRADIO's Julia Hartley-Brewer he’s “hopeful” his party will take action.
“It isn’t just about MPs and peers as much as the letter is coming from us. There’s also another one from Labour staff,” he said.
“It’s the members of our party who want our values upheld and want to have faith in Jeremy’s own words on this that he’s going to be militant on tackling antisemitism and it’s the number one priority."
The letter said Mr Williamson must lose the whip if the party has “any hope of persuading anyone that the Labour Party is taking antisemitism seriously”.
Mr Coyle said it’s a worrying trend for Labour.
“Our members do not miss, and the public do not miss the fact that this was not a problem under Ed Miliband or any other Labour leader for the last 100 years,” he said.
“Those who’ve taken this decision, and I believe it brings the party into disrepute, will have to answer for the process and why this has been fast-tracked.”
He added: “I had another case where someone had hit another member in the face and it took four months to get a decision.”
Yesterday Mr Corbyn said the party took all allegations of antisemitism "very, very seriously".
