Following Ken Livingstone's suspension, Jeremy Corbyn has insisted the Labour party is not in "crisis".
But it's been announced Livingstone will be investigated after he said Hitler had supported Zionism "before he went mad and ended up killing six million Jews".
And this isn't the first time the former Mayor of London has faced controversy. Far from it in fact...
Former shadow home secretary Yvette Cooper said the Labour party had been too slow to respond to complaints of anti-Semitism.
Corbyn - who has pulled out of a planned campaign visit to Wales - has insisted that any problem was confined to "a very small number of people" in the party.
