Naz Shah, the Labour MP suspended from the party amid accusations of anti-Semitism, has stepped down from the Home Affairs Select Committee.
The Labour MP quit her position as aide to the Shadow Chancellor John McDonnell last week after apologising for endorsing a social media post that Israelis should be transported to New York.
The influential committee was already due to investigate antisemitism in the UK.
It also confirmed that David Cameron, Ken Livingstone and Jeremy Corbyn will all be called to give evidence on anti-Semitism in UK.
Following some interesting conversations with key Labour personnel, here's where I think the party is right now.
Labour leader tells May Day rally his party 'stand absolutely against racism in any form'.
Dianne Abbott said the suggestion Labour had a 'problem' with anti-semitism was a 'smear'.
