Pete Willsman's rant about Labour antisemitism branded 'racist by any measure'

It accuses him of an "antisemitic slur" by "accusing religious leaders from across the Jewish community of not only being liars, but of acting as a fifth column for a foreign state".

"It plays directly to age old accusations of Jewish conspiracy, treachery and dual loyalty. It is racist by any measure," the letter says.

"It is also, ironically, one of the behaviours described as antisemitic in the definition of antisemitism that Labour’s leadership very grudgingly adopted last year, but have still failed to include anywhere on the Party’s website.”

The letter notes "how efficient Labour’s disciplinary processes can be when there is the will to make them so", a clear reference to the immediate expulsion of Alastair Campbell after he admitted voting for the Lib Dems.

In the recording of Mr Willsman's latest rant, revealed by LBC, he tells Israeli-American author Tuvia Tenenbom "off the record" that: "It's almost certain who is behind all this antisemitism against Jeremy. Almost certainly it was the Israeli embassy.

"They caught somebody in the Labour Party. It turns out they were an agent in the Israeli Embassy. My guess would be, they are the ones whipping it all up."

Deputy Labour leader Tom Watson said the recording "shows how serious the problem of antisemitism is in our party".
