A vote is to be held in early 2007 asking MP's whether the Trident nuclear weapons system should be replaced. The Trident system is due to go out of service in 2024 and Ministers are to select a replacement after a three-month consultation.
Commons leader Jack Straw said: "We have a responsibility not to cop out of this but to come to a decision, and we shall. "We're talking about defence of the nation here, not the Shops Act or fox hunting."
Mr Blair has said that Trident is an essential part of Britain's ability to defend itself.
With an estimated cost of up to £25bn, anti-nuclear campaigners say the money would be better spent elsewhere and they fear the government has already decided to go ahead with replacing Trident.
Kate Hudson, chairman of CND said a white paper could "close down" the wider debate.
Q. Should we replace Trident when it goes out of service in 2024?
