Activists from the hard-left Momentum campaign group are using the Israeli-Palestinian conflict to stir up tensions across Britain, MPs have claimed.

The warning came as a document investigating the alleged behaviour of Momentum members in Liverpool was leaked.

The report highlighted how Louise Ellman, the veteran Jewish Liverpool Riverside MP, had been targeted by activists in her constituency intent on getting her deselected ahead of the next election.

One Momentum campaigner was revealed to have suggested approaching Muslims to offer "a more progressive stance towards Palestine" while discussing whether Mrs Ellman could be removed. Another activist claimed she "uses her position as an MP to support whatever horrors the IDF and Israel commits".

A chain of emails uncovered in the investigation concluded with a campaigner claiming Mrs Ellman had a "martyred/victim look on her face" whenever antisemitism was raised at local party meetings.

In April, the JC revealed how Mrs Ellman had faced an orchestrated campaign, with activists "hell-bent" on attacking her at constituency party meetings.

Since the investigation report was leaked on Thursday last week, the JC has been contacted by non-Jewish MPs who believe similar action is being taken in their own Labour branches.

Mrs Ellman called on Labour "to take immediate action" following the revelations. "The antisemitic remarks that have come to light in this report are disturbing, but sadly unsurprising given the nature of recent party meetings," she said. "In the past year the Israel-Palestine conflict has been raised at meetings with increasing regularity with the intention of stoking up divisions within the CLP. It is clear in this report that figures within Liverpool Momentum have an almost obsessive focus on the state of Israel."

Momentum did not respond to a request for comment.
