Lord Mandelson reveals his daily struggle - to save Labour from Jeremy Corbyn
'I work every single day in some small way to bring forward the end of his tenure in office.'
Lord Mandelson last night branded Jeremy Corbyn a "maniac" and revealed he does something every day to try to unseat the Labour leader.
The architect of New Labour said the party was "on life support" but insisted it could be revived if Corbyn is replaced.
He made his outspoken comments while being interviewed by Jewish Chronicle editor Stephen Pollard in London last night.
According to the International Business Times, Lord Mandelson said: "The problem with Jeremy is not that he is a sort of maniac – it's not as though he is a nasty person.
"It's that he literally has no idea in the 21st Century how to conduct himself as a leader of a party putting itself forward in a democratic election to become the government of our country."
He added: "Why do you want to just walk away and pass the title deeds of this great party over to someone like Jeremy Corbyn?
"I don't want to, I resent it and I work every single day in some small way to bring forward the end of his tenure in office.
"Something, however small it may be – an email, a phone call or a meeting I convene – every day I try to do something to save the Labour party from his leadership."
The former Cabinet minister - who served under both Tony Blair and Gordon Brown - said Labour "is not dead and it can recover".
"It can pass out of the accident and emergency room in due course, if and when we get a new leader," he insisted.
The comments, made at a Jewish Chronicle event in London on Monday evening, drew a furious response from a Labour source who told HuffPost UK: “The idea of Jeremy Corbyn being Prime Minister and implementing policies that actually benefit the people terrifies the establishment.
“So it is no surprise Peter Mandelson has found time in his busy schedule of spending time on oligarch’s yachts to attempt to undermine him.”
Lord Mandelson hit the headlines in 2008 when he joined George Osborne on a yacht belonging to Russian tycoon Oleg Deripaska, as a guest of financier Nathaniel Rothschild.
Sources close to Corbyn last night insisted "the leadership question was settled" and dismissed suggestions that he had discussed a departure date with his close allies.
The Labour leader also told Labour MPs the media was to blame for the party's poor ratings, after a poll yesterday put them 18 points behind the Conservatives.
He said: "Of course I understand what's going on and the problems we have had in the media.
"We need to get a strong, positive message across and we do that better on social media."
