Two Labour MPs clashed with John McDonnell on live TV over the party’s handling of antisemitism, hours after MP Chris Williamson was suspended.
On Wednesday it was announced that the party was investigating Mr Williamson's “pattern of behaviour”, following complaints about his actions over the Labour antisemitism row – but declined to initiate further disciplinary measures.
After an outcry from MPs, he was suspended, and the Labour whip was withdrawn.
Appearing on ITV’s Peston on Wednesday evening, Mr McDonnell denied the party had been too slow to act.
