Jeremy Corbyn has tasked Labour’s new general secretary, Jennie Formby, with drawing up an “action plan” for tackling antisemitism in the party.
The plan will be discussed at the first meeting of the shadow cabinet after Easter, with new measures likely to be introduced to speed up the process of dealing with allegations.
The Labour leader acted after hundreds of people join a protested outside Parliament criticising his response to anti-Jewish sentiment.
He confirmed that both he and Ms Formby will attend the next meeting of the Parliamentary Labour Party to listen to MPs' concerns.
In a letter to Labour MPs on Wednesday, seen by The Independent, he wrote: “Following recent events and the [Parliamentary Labour Party] meeting on Monday, the shadow cabinet held an open and extremely constructive discussion on tackling antisemitism in the Labour Party.
“I was grateful to hear the perspective of so many colleagues on the issue of antisemitism. It was very clear that we are unanimous in our determination, along with the new general secretary, Jennie Formby, to tackle this issue immediately and effectively.
“I have already asked Jennie to consider an action plan as a priority and invited her to come to the first shadow cabinet meeting after the Easter recess to discuss it. We will both be attending the next PLP meeting.”
Mr Corbyn said new measures would include the full implementation of the recommendations of Shami Chakrabarti’s report on the issue, and efforts to speed up the way in which allegations antisemitism are deal with.
Labour will also introduce a “programme of political education to increase awareness and understanding of all forms of antisemitism”.
Mr Corbyn is also seeking an “urgent meeting” with Jewish representative groups theBoard of Deputies and the Jewish Leadership Council, although reports suggest they are reluctant to meet with him at the current time.
The Labour Against Antisemitism group has previously raised concerns about Ms Formby's ability to tackle antisemitism in the party.
The Independent revealed earlier this month that she was involved in giving a job to Vicki Kirby, who had previously been suspended for saying Jews have "big noses" and "slaughter" people, and calling Adolf Hitler "a Zionist God".
