Commons ChamberThe costs of the alternatives review are met from existing departmental budgets and no additional costs will be associated with it. As I have said, when we take into account the different developments, including the fact that we have taken costs out of the missile compartment, as the right hon. Gentleman correctly says, and have reassessed the infrastructure required, we believe that there has been no additional net cost to the programme on the 2006 prices.
Whatever my right hon. Friend’s openness of mind, does he personally agree that the real choice is between a ballistic system and no nuclear deterrent at all? Although there are perfectly respectable arguments for both propositions, the idea of having a vulnerable cruise-based system misses the point of nuclear deterrence altogether.
I have made it clear on a number of occasions why I believe that having a ballistic, submarine-based system providing continuous at-sea deterrence is the only way to guarantee the level of deterrence that this country has come to regard as the minimum credible level. A number of disadvantages relate to any cruise system, including the fact that the missiles are more vulnerable to anti-missile defences, that they are slower and that there are cost implications because we would require more of them and more platforms from which to launch them. I am very relaxed about any consideration of the alternatives because I believe that anyone who has looked at the criteria and the information behind the 2006 White Paper will rapidly come to the conclusion that if we want a minimum credible nuclear deterrent for the United Kingdom, this system, which will be provided by the replacement Trident system, is the best and in fact the only credible one.
