Trident

Mr Gale, without wishing to trivialise this very important subject in any sense, I had intended to begin my remarks by a reference to that famous line of Captain Louis Renault about rounding up the usual suspects at the end of ““Casablanca””, but the number of usual suspects seems to have expanded today to a rather larger number than I had expected. I had imagined that only the hon. Member for Islington North (Jeremy Corbyn) and my hon. Friend the Member for New Forest East (Dr Lewis) would be in Westminster Hall today, but I welcome the larger group of actors. I am delighted to be in Westminster Hall once again to explain to the hon. Member for Islington North why we are right to proceed with our plans to maintain the security of our nation and why I think that he made a number of serious misinterpretations of the facts—let me put it that way—during his speech. The Government have been clear that the safety and security of the UK is our first priority, and although we are facing difficult economic circumstances and a challenging inheritance from the previous Administration, our security must be seen as a long-term issue. At the outset and on behalf of the whole House, I want to pay tribute to the professionalism of all those Royal Navy and civilian personnel who answer this country's call to operate and support this vital national capability. Having visited HMS Vanguard at sea and HMS Vigilant in refit, I have met some of our dedicated service personnel who support Operation Relentless, which is the UK's mission to maintain continuous at-sea deterrence. I was deeply impressed by their commitment and I am very grateful to them; I think that we should all be grateful to them. It is important that hon. Members remember that, even as we speak, those men are out there somewhere in the oceans providing Britain's ultimate national security guarantee. They and their predecessors have maintained a 42-year unbroken chain of continuous at-sea deterrence, keeping all of us and our allies safe. In many respects, we face a more dangerous situation now than we have done for several decades. There are substantial risks to our security from emerging nuclear weapon states. Consequently, although we are committed to the long-term goal of a world without nuclear weapons, as we all are in this place, we believe that we can best protect ourselves against those threats by the continued operation of a minimum, credible nuclear deterrent. [Interruption.] Others might find that funny, but I do not find it funny at all. Maintaining that deterrent is a very serious judgment that is shared by all three major parties in the House. It is important to remember that the alternative study, which I will return to later, which has been promised to the Liberal Democrats and which is proceeding, only considers the delivery platform and not the alternative to a minimum credible national deterrent programme. All three major parties are committed to such a programme. The UK has a strong record on nuclear disarmament. We have continued to work with other nations to achieve our goal of a world without nuclear weapons. In addition to the well-documented commitments in the strategic defence and security review, I draw the attention of the hon. Member for Islington North to the statement in June that we have already begun to implement the reduction in warheads that are carried on our submarines. In addition, earlier this year, the permanent members of the UN Security Council met in Paris to take forward the action plan from the 2010 non-proliferation treaty review conference. We agreed to work together on a number of initiatives and Britain has taken the lead by agreeing to host a meeting in early 2012 to discuss the lessons that have been learned from our bilateral work with Norway on the verification of nuclear weapon dismantlement. Having set out the Government's fundamental policy, I want to address one further issue before I turn to the specific details of Trident's costs. One theme that frequently emerges—it emerged again today in the hon. Gentleman's speech—is the engagement with Parliament on the replacement of the nuclear deterrent. The hon. Gentleman's colleagues in CND often accuse the Government of having a culture of secrecy with regard to the deterrent. Clearly, there are aspects of the programme that are sensitive and that must remain classified for national security purposes. I will also discuss the Trident alternative study in that regard. The Government have received many requests, including from the hon. Gentleman in his speech, for information on the Trident alternatives study. The nature of that study, which is led by the Cabinet Office, requires highly classified information to be analysed. Indeed, only a small number of people in my Department and in the Cabinet Office can see that information. Therefore, Members will appreciate that we will not be able to publish the study itself, as doing so would be irresponsible and put national security at risk. No decisions have yet been taken about what it might be possible to say without compromising national security, and as the report to the Prime Minister and the Deputy Prime Minister will not even be concluded until late 2012 or early 2013, it would be premature at this stage to commit to any specific course of action; for that reason, I will not be doing so today. I have no doubt that the public would understand that we want to take great care of those secrets, but we have nothing to hide except that which it is essential to hide for national security. Where we can, we have explained as clearly as possible what we are doing and why we are doing it, and I will do so yet again today for the hon. Gentleman's benefit.
