Strategic Defence and Security Review

Prompted by my hon. Friend, I am delighted to say, as he will know, that in the SDSR and in our Trident value-for-money review the Government committed to renewing the independent nuclear deterrent: submarine-based, continuously at sea, patrolling. That programme is being taken forward. Initial gate was in May last year, and I assure him that all the work is continuing and in progress. If I may, I also take this opportunity to salute my hon. Friend, my hon. Friend the Member for Gainsborough (Mr Leigh), and Tony Kerpel on the then coalition, because I supported it at the time and am delighted to be in government supporting it now.
