“You have to feel absolutely confident that it is totally unacceptable and it won’t be tolerated and I personally haven’t felt comfortable that it is happening yet in the Labour party.”

Mr Cohen, who stepped down from his BBC post in November, added: “I am deeply troubled about what is going on in the Labour Party. I am deeply troubled that our main opposition party is having such frequent problems with antisemitism. It really disturbs and troubles me.”
His remarks come after widespread condemnation over Mr Corbyn’s apparent failure to tackle Jew-hate in his party, after he welcomed back members who had made antisemitic comments.
But Mr Corbyn has repeatedly said he is “absolutely resolute” in combatting antisemitism.
