Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what recent assessment he has made of the cost effectiveness of the Trident programme over the last five years.
We regularly review all major programmes to ensure that they operate in the most efficient and effective manner possible. The 2010 Trident Value for Money study and the 2013 Trident Alternatives Review both confirmed the cost effectiveness of a Trident-based deterrent on continuous patrol.
