Corbyn and McDonnell accused of 'breaching own guidance on antisemitism' with Holocaust Memorial Day motion

Also sponsoring the motion was the now Labour leader Mr Corbyn.

The Never Again For Anyone motion noted that "disabled people were the first victims of Nazi mass murder" and that "Nazism targeted not only Jewish, but also Roma, Jehovah's Witnesses, lesbian, gay and bisexual people and others deemed undesirables."

Calling for Holocaust Memorial Day to be renamed Genocide Memorial Day - Never Again For Anyone it declared that "every life is of value."

The motion was tabled on Holocaust Memorial Day itself.

One furious source who spoke to the JC on Monday said: "John McDonnell and Jeremy Corbyn have breached their own guidance on antisemitism.

"Today we are advised that denial, revisionism and minimisation constitutes antisemitism, yet in 2011 they were guilty of it through this disgraceful EDM.

"Maybe if the Labour Party had engaged with the Jewish community rather than mansplaining what is antisemitic, we would not be in this sorry situation.

"The irony is not lost on any of us."

No Place For Antisemitism was issued to party members on Sunday.

It was accompanied by an email from Mr Corbyn, in which he wrote: "We must face up to the unsettling truth that a small number of Labour members hold antisemitic views and a larger number don't recognise antisemitic stereotypes and conspiracy theories.”

The Jewish Labour Movement said the attempt by Labour to produce the resource to tackle hate was "too little, far too late."

A Labour spokesperson said:“This claim is false and illogical. Recognising other genocides does not minimise the horror of the Holocaust nor is it Holocaust denial or revisionism.”
