eremy Corbyn has promised to lead a Labour "fight back" after being elected the party's new leader by a landslide.
The veteran left winger got almost 60% of more than 400,000 votes cast, trouncing his rivals Andy Burnham, Yvette Cooper and Liz Kendall. He immediately faced an exodus of shadow cabinet members - but senior figures including Ed Miliband urged the party's MPs to get behind him.
Mr Corbyn was a 200-1 outsider when the three month contest began.
But he was swept to victory on a wave of enthusiasm for his anti-austerity message and promise to scrap Britain's nuclear weapons and renationalise the railways and major utilities.
He told BBC News he had been a "bit surprised" by the scale of his victory but his campaign had showed "politics can change and we have changed it".
He will now select his shadow cabinet - but without a string of existing members including Ms Cooper, Tristram Hunt and Rachel Reeves - who have all ruled themselves out.
