Oral question asked in the House of Commons, by Lord Walney (Labour). It was answered on Monday, 31 January 2011 on behalf of the Ministry of Defence.

Trident Replacement Submarines

Question: May I say how pleased I was to accompany the Minister with responsibility for procurement, the Under-Secretary of State for Defence, the hon. Member for Mid Worcestershire (Peter Luff), around Barrow shipyard a couple of weeks ago? The Defence Secretary knows that of the £3 billion of so-called savings in the Trident value-for-money review, more than half are deferments. Will he tell the House the increased cost of deferment, and why he thinks that approach is acceptable, given how often he spoke out against it when he was in opposition?

Answer: There are two imperatives. The first is to ensure that we have the successor programme. The second is to ensure that we do it within the financial constraints that the Government are forced to take on board, given the economic position that we inherited. Through the value-for-money study, as the hon. Gentleman well knows, we looked to see how we could extend the life of the current programme, if possible, to minimise the expenditure in early years. That is helpful not only in reducing the deficit in the period set out by the Government, but in ensuring the success of the programme itself.
