Defence: Trident Replacement Programme

Lord Lea of Crondall Excerpts

Tuesday 19th June 2012 Lords Chamber

Asked by

[Lord Lea of Crondall]

To ask Her Majesty’s Government what is their assessment of the consequences for nuclear non-proliferation of proceeding with a Trident replacement programme.

[The Parliamentary Under-Secretary of State, Ministry of Defence (Lord Astor of Hever)]

My Lords, first, I am sure that the whole House will wish to join me in offering sincere condolences to the families and friends of Captain Stephen Healey of the 1st Battalion The Royal Welsh; Corporal Michael Thacker of the 1st Battalion The Royal Welsh; Private Gregg Stone of the 3rd Battalion The Yorkshire Regiment; Lance Corporal James Ashworth of the 1st Battalion Grenadier Guards; and Corporal Alex Guy of the 1st Battalion The Royal Anglian Regiment, who were killed on operations in Afghanistan recently. My thoughts are also with the wounded and I pay tribute to the courage and fortitude with which they face their rehabilitation.

I turn to the Question. The nuclear non-proliferation treaty, the NPT, does not require unilateral disarmament. Maintaining the UK’s nuclear deterrent beyond the life of the current system is fully consistent with our obligations. There is also no evidence or likelihood that others would follow the UK down a unilateralist disarmament route. We will achieve sustainable global nuclear disarmament only through a multilateral process, and the NPT represents the best means currently available for pursuing this.

[Lord Lea of Crondall]

My Lords, on the very sad news from Afghanistan, I am sure that everyone on this side of the House will wish to endorse the sentiments expressed by the Minister and his condolences to the five families concerned. The premise of my Question is multilateral, not unilateral. It is the Government who are, in practice, trying to ride both horses. Recent researches for the Trident Commission show that the nuclear powers will be spending $1 trillion—$1,000 billion —over the next 10 years. How does the Minister expect the non-nuclear states who have signed the non-proliferation treaty to stick to their side of the deal—the grand bargain—unless the likes of us stick to it too? Secondly, the very well-informed defence correspondent of the Evening Standard reported yesterday a “decision by stealth” to go for full Trident replacement. Why are the people of this country not entitled to a national conversation about the pros and cons of where we should be heading as we approach the so-called “main gate” decision in 2016?

[Lord Astor of Hever]

My Lords, we are committed to retaining the minimum credible nuclear deterrent capability necessary to provide effective deterrents, and we keep that under constant review. At the same time, we are working multilaterally for nuclear disarmament and to counter nuclear proliferation. We believe that this is the right balance between our commitment to long-term disarmament and our responsibilities to ensure our national security. I do not accept the noble Lord’s point about stealth. So far as concerns a public debate, a main gate is not expected until about 2016. A decision about how best to consult will be made nearer that time.
