Jeremy Corbyn has been suspended from the Labour Party because his reaction to damning report about antisemitism in the party while he was leader.

The investigation by the Equality and Human Rights Commission found the party was responsible for unlawful acts of harassment and discrimination.

Mr Corbyn rejected some of the report’s findings and claimed the issue had been “dramatically overstated for political reasons” by his critics.

Sir Keir told reporters: “If – after all the pain, all the grief, and all the evidence in this report – there are still those who think there’s no problem with anti-Semitism in the Labour Party, that it’s all exaggerated, or a factional attack, then, frankly, you are part of the problem too.

“And you should be nowhere near the Labour Party either.”

Sir Keir said the findings of the EHRC investigation marked a “day of shame” for Labour and he was “truly sorry” for the pain caused.

Mr Corbyn denied he was “part of the problem” and told broadcasters he would not quit Labour: “Of course not. I am proud to be a member of the Labour Party, I joined the Labour party when I was 16, I’ve fought racism all my life, and I’ll fight racism for the rest of my life.”

In a broadcast interview he said: “The numbers of cases in the public perception had become overstated.

“The existence of the problem, I fully acknowledge, which is why I took action to end the problem in the party by introducing a process to get anti-Semites out of the party.”

“He has also had the whip removed from the Parliamentary Labour Party.”

Responding to the news Jeremy Corbyn has been suspended from the Labour Party, Conservative Party co-chairman Amanda Milling tweeted: “Many will be asking themselves why it took this long to act.

“This morning (Sir Keir Starmer) failed to say seven times that he would take action against Corbyn and now he has been pushed to do so. Hardly leadership.”

Labour MP Harriet Harman said Mr Corbyn’s suspension is “the right thing to do”.

“This is the right thing to do,” Ms Harman tweeted.

“If you say that AS exaggerated for factional reasons you minimise it & are, as @Keir_Starmer says, part of the problem.”

Labour Mayor of London Sadiq Khan said the EHRC marks “a dark day” for the party.

“It’s utterly shameful that, rather than being an ally and defending the Jewish community, the Labour Party not only failed to address anti-Semitism within the party, but oversaw unlawful acts of harassment and discrimination,” he said in a statement posted to Twitter.

“I welcome Keir Starmer’s swift and strong response to the EHRC report, as well as the action he’s already taken as leader to root out anti-Semitism.

“I will do everything I can to work with the new leadership of the Labour Party to stamp out anti-Semitism and to bring an end to this appalling chapter in Labour’s history.”
