'In December 2006 the Labour Government published a white paper entitled The Future of the United Kingdom’s Nuclear Deterrent which set out the Government’s goals and principle recommendations for replacing the UK’s nuclear deterrent beyond the 2020s. A debate and vote in the House of Commons on the general principle of whether the UK should retain a strategic nuclear deterrent beyond the life of the current system was subsequently held on 14 March 2007 in which the Government motion was approved by 409 to 161 votes.
However, the debate on the feasibility of replacing the UK’s nuclear deterrent in the current economic and political climate is ongoing. Many commentators have thus called for a further debate and vote in the House of Commons before the programme is taken any further forward.
The following is a list of suggested reading material which provides background on the decision to replace the nuclear deterrent, the international legal context for such a decision and the current debate on financial and political viability, including the impact of the programme on the wider Strategic Defence and Security Review, which is due to report in the autumn.'
