A Labour government that will end austerity could come "sooner than you think," shadow international development secretary Barry Gardiner told the People's Assembly Change is Coming conference at the weekend.

Mr Gardiner said Theresa May's administration could fall apart at the seams when Parliament considers whatever deal she obtains on Brexit terms this autumn.

An early election could propel the most radical Labour government in memory into office, he said, and that government would not only reverse Conservative spending cuts but redefine Britain's relationship with the world, rejecting corporate trade deals like Ceta and TTIP and stopping arms sales to murderous regimes "starting with Saudi Arabia."

"I know we're all tired of elections," he told the crowd in St Pancras New Church, London. "They seem to happen more often than the private rail franchise collapses on the East Coast Main Line.

"But think of the possibilities and feel the excitement."

He saluted the work of the People's Assembly as the first mass campaign against austerity, saying it had been proven right by events.

Mr Gardiner's was the final address of the all-day conference which saw hundreds of labour movement activists debate issues including nationalisation, taking on the mainstream media, the role of local authorities in resisting austerity and the housing crisis.

Earlier, shadow chancellor John McDonnell outlined the role of a national investment bank in promoting regional development and a sustainable industrial strategy for the country while shadow home secretary Diane Abbott discussed the positive impact of immigration.
