The Prime Minister has said that former Labour politicians Clement Atlee and Aneurin Bevan – who established the NHS - would be “spinning in their graves” over his treatment of the Labour party.
Theresa May accused the Labour leader of putting his party politics before the national interest, and “frustrating” the possibility of a Brexit deal.
Speaking in the House of Commons, Mrs May said: “We can take no deal off the table by agreeing a deal and yet at every stage he has acted to frustrate a deal. He has acted to make no deal more likely.
“That is not surprising from this Labour party because what do we see from his Labour party.
“Hamas and Hezbollah – friends. Israel and the United States – enemies.
“Hatton is a hero and Churchill is a villain. Atlee and Bevan will be spinning in their graves.
“That is what the right honourable gentleman has done to a once proud Labour party. We will never let him do it to our country.”
Watch: Theresa May attack Labour over 'institutional anti-semitism'.
When asked a question on tackling anti-semitism, Mrs May said he would have thought Labour would be “accused of institutional anti-semitism by a former member”.
“I never thought I would see the day when Jewish people in this country were concerned about their future,” she said.
“I never thought I would see the day when the once proud Labour party was accused of institutional antisemitism by a former member of that party.
“It is incumbent on all of us in this house to ensure that we act against antisemitism wherever and however it occurs. It is racism and we should act against it.”
Mr Corbyn said that the Labour party was taking the “strongest action” to deal with anti-semitism within the party.
“It has no place whatsoever in our society or in any of our political parties,” he said.
“My own political party takes the strongest action to deal with antisemitism wherever it rears its head.”
