Strategic Defence and Security Review

The hon. Gentleman presumably hopes that that will be the case in the future. However, I challenge him to point to any other defence programme from which he could extrapolate that conclusion. I know that he follows these matters with care, but I cannot think of another programme. He is right to point out the special cases of those procurements in the past, but I am not reassured that they will be repeated in the future. In any event, that point is not at the heart of my case. No matter how one looks at it, this is a very large sum of money to spend. My point is that we should look carefully at whether we should spend it. The maingate decision on final renewal has been pushed back until after the next general election. The cost of that is said to be an additional £1.5 billion to refurbish and prolong the lifespan of the existing fleet. Parliamentary answers from Defence Ministers show that upwards of £2 billion has already been spent on preparatory work for the manufacture of the new submarines. The Government clearly intend to press ahead with Trident renewal. In my opinion, they should seek explicit parliamentary authority for doing so. The failure to hold a vote in Parliament on the renewal of our independent nuclear deterrent is because of the inability to reconcile different views in the coalition. The question that faces us is whether an independent nuclear deterrent is a good use of such a large sum of public money in the present circumstances. The arguments, which were never that strong, are now moving away from Trident renewal.
