Supporters of Jeremy Corbyn have demanded an apology from Jewish MP Luciana Berger after they took control of the Labour Party group in her constituency.

Nine out of ten positions on the Liverpool Wavertree branch executive committee were filled by members of Momentum, the left-wing grassroots organisation established to support Mr Corbyn after his election as Labour leader.

A member of the new executive immediately demanded an apology from Ms Berger for resigning from Mr Corbyn’s shadow cabinet last summer in the wake of the EU referendum result.

Roy Bentham, who is not a member of Momentum, also said Ms Berger “needs to get on board quickly”.

In a joint statement with the new constituency Labour Party secretary Angela Kehoe Jones, Ms Berger praised Mr Corbyn, saying she wants a “return of a Labour government under the leadership of Jeremy Corbyn as soon as possible”.

Last year, another Jewish Liverpool MP, Louise Ellman, called for the suspension of Momentum activists over fears they were trying to oust her.

The JC revealed in April 2016 a campaign of “terrifying” abuse against Mrs Ellman by Momentum activists. One councillor in her Liverpool Riverside constituency said it created an “intimidating and hostile” atmosphere for Jewish members.

A small group of hard-left activists attended the sessions specifically to attack her, asking questions only about her position on Israel. The JC understood that antisemitic remarks were made on at least three occasions.

Momentum denied it targets Jewish MPs or Labour MPs generally, describing such accusations as "completely baseless". 

A Momentum spokesman said: "The idea that someone would (target Jewish MPs) is utterly reprehensible. Momentum is focused on fighting for a Labour victory in the next election, and that is why we're rolling out a nationwide training programme, canvassing in new marginals outside of a election time and launching new tech tools to make it easy for members to get involved in the Labour Party."

In September 2016, the Echo reported on efforts by left wing members to take over key positions within Mrs Ellman’s seat.
