Labour MPs say Shadow Cabinet members ‘actively complicit’ in smearing antisemitism whistleblowers

They urged Mr Corbyn and his shadow cabinet “not to waste” the opportunity “individually, and collectively, you are the leadership of the Labour Party. It is time for you to step up to the mark.”

The plea also notes the letters sent last Friday to the shadow cabinet from the Board of Deputies and the Jewish Leadership Council.

It adds: "The JLC and the Board of Deputies are the representative bodies of British Jewry. They do not claim to speak for every Jewish citizen, but they do speak for a majority. 

"The Board has urged you to turn the tide against antisemitism within our ranks and have outlined the minimum steps they would expect the Labour Party to take in order to start this process. The JLC have urged you to examine your consciences and have also made it clear that to be silent is be complicit.”

It also refers to the GMB Labour staff union vote condemning the leadership's response to antisemitism complaints.

Labour staff voted overwhelmingly for a motion condemning the party’s response to last week’s BBC Panorama documentary, which saw it attack whistleblowers who spoke out about antisemitism.

On Thursday, party staff represented by the GMB trade union voted 124 to four for a motion that demanded the party apologise and affirms support for whisteblowers, after Labour hit out at "disaffected" ex-staffers who spoke to journalists about the party's Jew-hate crisis.

The letter to the shadow cabinet stated: "Aside from the fact that a number of those who appeared on the Panorama programme voted twice for Jeremy Corbyn to become Leader of the Labour Party, the resolution passed this week by the GMB Labour staff branch must surely serve as a wake up call to those members of the Shadow Cabinet who continue to labour under the delusion that complaints about our handling of antisemitism cases, and the culture of the Labour Party’s leadership and management, are motivated by those with an axe to grind.”
