Michael Foster, a Jewish donor to the British Labour Party, likened party head Jeremy Corbyn’s leadership team to “Nazi stormtroopers” in an op-ed published on Sunday.

Foster donated £400,000 to the party in the last election.

In an op-ed published by the Mail on Sunday titled, “Why I despise Jeremy Corbyn and his Nazi stormtroopers,” Foster berated the leadership of the British Labour Party.

Foster described the inner circle around Corbyn as his “Sturmabteilung” – the name of the Nazi’s SA “Brown shirt” stormtroopers.

The remarks came after Britain’s Court of Appeal strengthened the sole leadership challenger, Owen Smith, by ruling that 130,000 new members to the party could not vote in the race that ends on September 21. These members are thought to back Corbyn.

“This [earlier court] decision [to allow the new members to vote] advantaged Corbyn and his Sturm Abteilung (stormtroopers), but on Friday afternoon the Appeal Court handed down a big decision for British democracy,” Foster wrote.

He also wrote, “If you are like me, a Jewish donor to Labour, you are smeared as a Blairite conspirator, plotting to falsely use the accusation of anti-Semitism to damage the Left.... Corbyn and his leadership team have no respect for others and worse, no respect for the rule of law.

“They clearly have no moral compass, and in Corbyn they have a leader who wants to abolish the House of Lords yet is happy to confer and defend the granting of a peerage on Shami Chakrabarti, whose detailed report into anti-Semitism in the Labour Party was anything but independent....

“Oppose them as a Jewish donor and the riposte from Seumas Milne, Corbyn’s mouthpiece, is that you are part of a Blairite, Right-wing ‘conspiracy’ (the ancient racist rhetoric is that Jews don’t act alone, the malevolent Jew always conspires) to destabilize the democratically and legitimately elected leader,” Foster wrote in the Mail on Sunday.

Foster’s remarks are the latest in a series of allegations connected to anti-Semitic incidents within the Labour Party.

During the past few months the Labour Party has been fractured with Corbyn’s leadership with as many as 230 MPs considering to break away.

Earlier in the summer, more than 170 Labour MPs voted for a no-confidence motion regarding Corbyn.

During the past few months there have been several high-profile suspensions from the Labour Party due to anti-Semitic scandals.
