Labour agreed to include Britain’s cold war-era nuclear weapons in a review of defence capabilities yesterday — but delegates to the party’s annual conference will be denied a vote on scrapping Trident.

Party members’ representatives were repeatedly propositioned with suggested compromises at Labour’s national policy forum in Milton Keynes — including a commitment to multilateral disarmament.

But they continued to threaten to push the issue to a vote — until shadow defence ministers reluctantly agreed to a stronger wording late on Saturday night.

If the issue had attracted more than 25 per cent in a vote the decision would have been referred to Labour’s September conference.

The party’s official policy now says: “The process and debate leading up to the next Defence and Security Review in 2015 needs to be open, inclusive and transparent, including examining all capabilities, including nuclear.”

Labour had previously refused to make such a commitment.

Around 45 constituency Labour branches submitted amendments calling for Britain’s Cold War nuclear weapons system to be scrapped, while a “deliberative workshop” saw Left Labour MP Jeremy Corbyn warn delegates on the dangers and wastefulness of replacing warheads.

Labour CND activist Daniel Blaney said: “I’m glad the party establishment has recognised that they have to give way on this issue — it shows they’ve noticed the protestations of grass-roots activists and the likes of John Prescott, who has recently called for Trident to be scrapped.

“But I’m disappointed that there won’t be a vote at annual conference on this issue, given the number of CLPs who supported scrapping Trident in their submissions to the NPF.

“There is a huge strength of feeling in the party about this — and they should stop attempting to silence members.”
