Ms Morgan, the former Conservative Education Secretary, blasted Mr Williamson for his remarks and repeatedly asked him if he backed Ken Livingstone’s expulsion from Labour.
Ms Morgan praised Labour MPs who spoke movingly about their experiences of antisemitism on the British Left at a debate in parliament on Tuesday.
She said: “People need to understand the extraordinary scenes that we have seen, including a truly remarkable speech from Ruth Smeeth.”
Ms Morgan went on to criticise “people giving the Labour MP Luciana Berger a hard time”.
She told Mr Williamson: “Labour members of Bristol West who made the Labour MP Thangam Debbonnaire pass a motion - or wanted to criticise her - for attending a rally about antisemitism in Parliament Square are nothing to do with the right. Call them out.”
At one stage Mr Williamson responded by banging his fist on the table and talking over Ms Morgan and also refered to her as “woman”.
On Monday Mr Williamson spoke at the Stop the War demonstration in Parliament Square and attacked Israel. He also applauded a band a performance on stage in Westminster by a guitar duo who performed a song with lyrics that labelled Israel an "apartheid" state and "a living hell".
