Theresa May has called for Labour MP Chris Williamson to be suspended during Prime Minister's Questions, following his comments that the Labour Party had been "too apologetic" over antisemitism claims.
Addressing the House of Commons, Ms May said it "sums up" Labour's leadership that Luciana Berger had left the party over alleged antisemitism, and Mr Williamson remained.
"You can never be 'too apologetic' about antisemitism, but I think what we've heard sums up Labour under their leader," Ms May said.
"They lose the MP for Liverpool Wavertree, and they keep the MP for Derby North."

She added: "Perhaps if the Labour leader actually wants to take action against racism, he would suspend the MP for Derby North."
Her comments were met with cheers from both sides of the Commons.
Mr Williamson issued an apology for his comments on Twitter this afternoon, writing that he had been an "anti-racist" all his life.
"It pains me greatly, therefore, that anyone should believe that it is my intention to minimise the cancerous and pernicious nature of antisemitism," he wrote.
