Dr. Howells The Government are strongly committed to the nuclear non-proliferation treaty (NPT), which is the cornerstone of the nuclear non-proliferation regime.

Jeremy Corbyn To ask the Secretary of State for Foreign and Commonwealth Affairs what advice she has received from her officials supporting the view that it is necessary to make a decision on Trident replacement in 2006; and if she will make a statement. Dr. Howells The Foreign and Commonwealth Office (FCO) and the Ministry of Defence jointly produced the White Paper on the Future of the UK's Nuclear Deterrent. FCO officials were closely involved in all the preparatory analysis, including the realistic life of the Vanguard class ballistic missile submarines and the time required to develop replacements. The outcome of these discussions was that if we were to maintain unbroken deterrent capability, decisions needed to be taken now on whether to replace those submarines.
