“I was told that in the leader’s office. When I went in and I had a meeting and said I have had these meetings these organisations, I’m really concerned about what’s happening and a break down in trust and I was told it wasn’t for me as shadow foreign secretary to be raising this.”

Asked whether it was Mr Corbyn she had spoken to, she replied: “Not by Jeremy Corbyn, but by those around him.”

It comes after the Islington South and Finsbury MP accused Ms Long-Bailey of failing to push for tougher action of antisemitism, telling BBC Newsnight that she did not “remember” her colleague speaking out in the shadow cabinet.

“It also should be said that Keir and I were both in the shadow cabinet and would regularly, the two of us, call for regular reports to the shadow cabinet,” Ms Thornberry said on Wednesday evening.

Ms Long-Bailey disputed her claim and said she would sign up to the 10 pledges on tackling antisemitism in the party that has been set out by the Board of Deputies of British Jews if she wins the Labour leadership contest on 4 April.

"As leader I will be signing up to the 10 pledges. I would expect my shadow cabinet and all those within it, all our members and MPs within parliament to follow my lead on that," she added.

Ms Long-Bailey also said the party did not deal “swiftly” enough with accusations of antisemitism in Labour’s ranks, adding: “I agree that not enough took place and we didn’t take the action that was required.”
