The Board and the JLC have already asked that an independent ombudsman be appointed to examine allegations of antisemitism and that the ombudsman reports to both the Labour Party and the Board.
“This is the Labour leader’s final opportunity to deliver on antisemitism. I am not prepared to negotiate. We have set out expectations and expect him to act,” Mr Arkush said.
The organisations took the took the unprecedented step of demonstrating outside Parliament in March before delivering an open letter to a meeting of Labour MPs and peers about their concerns.
Following the protest, Mr Corbyn said he was “happy to meet” the two bodies “without any preconditions” and vowed to hear their concerns about tackling antisemitism in the Labour Party.
Referring to the "Enough is Enough" demonstration organised by their groups, the Jewish leaders wrote: "Last month’s protest was a necessary moment of catharsis, as painful for Labour as it was for our community, but we cannot now return to 'business as usual'.
"We need this to be a genuine turning point and will do everything we can to make it so.
"We can achieve this together if Mr Corbyn can fulfil his pledge to be our 'militant ally' in the fight against antisemitism and demonstrate his understanding that what is now needed is firm action and not just words."
The meeting will also be attended by Jennie Formby, Labour general secretary.
