The Government are strongly committed to the Nuclear Non-Proliferation Treaty (NPT), which is the cornerstone of the nuclear non-proliferation regime. The UK is determined to make every effort to ensure that this review cycle results in a positive and substantive final document. We will work with allies and EU partners at the May 2007 NPT Preparatory Committee to lay the groundwork for this. We have already made a contribution by announcing, in the White Paper on the Future of the UK's Nuclear Deterrent, a further 20 per cent. cut in our warhead stockpile.
