Labour will not debate the future of Britain's nuclear deterrent, after the motion on its future was defeated in the priorities ballot.

A motion on the Trident system had been entered into the priorities ballot along with issues ranging from the refugee crisis to the NHS. Eight out of the twelve priority motions will be debated fully, after a Conference vote to decide the last eight.

Trident, a totemic issue within the Labour party, had been expected to make it through. But a deal between Labour's trade unions saw the Trident motion blocked off, after union delegates used their votes to ensure other issues topped the pile.
