The party leader said if he became Prime Minister he would negotiate a new Brexit deal with Brussels and then put it to a public vote. Mr Corbyn would ask the nation to choose between his divorce deal and staying in the EU but hinted he would not campaign in favour of either. His stance on the subject has sparked a wave of fury and prompted accusations Mr Corbyn wants to continue sitting on the fence over Brexit.
It comes just days before Labour’s annual conference in Brighton is due to get underway.

His opponents also suggested he was guilty of a “shameful abdication of leadership”.
