Labour's ruling body and the shadow cabinet have "unanimously" backed the party's draft general election manifesto following a joint meeting in central London on Thursday 11 May.

The vote came just hours after a copy of the manifesto was leaked to the press. Both Labour HQ and Jeremy Corbyn's team denied they were the source of the document being made public.

"We've just concluded our joint meeting of the shadow cabinet and the National Executive and we've discussed our manifesto for the general election," Corbyn said.

"We've just unanimously agreed the content of it. We've amended a draft document in the most informed, interesting and sensible debate."

The Labour leader claimed the policies, including re-nationalising the UK's railways, energy firms and the Royal Mail, would "transform the lives of many people in our society". The full and amended manifesto will be published over the next few days, Corbyn said.

"The commitments in this dossier will rack up tens of billions of extra borrowing for our families and will put Brexit negotiations at risk," a Conservative spokesperson said. "Jobs will be lost, families will be hit and our economic security damaged for a generation if Jeremy Corbyn and the coalition of chaos are ever let anywhere near the keys to Downing Street."

The latest opinion from YouGov, of more than 1,600 voters between 9 and 10 May, put the Conservatives 16 points ahead of Labour (46% versus 30%).
