Defence: Continuous At-Sea Deterrent — House of Lords, 2016-07-13
Topic: Defense
Julie Smith (Liberal Democrats, Centre to centre-left): My Lords, I am going to wind up for the Liberal Democrats and will probably give the only—dare I say it—authentic and official Liberal Democrat position on continuous at-sea deterrence. I will say in advance that I am speaking as briefed according to our party policy. I speak as vice-chair of our Federal Policy Committee and as the person who has the dubious distinction of chairing our last defence working group. We produced an excellent defence policy paper, most of which I would be very happy to advocate to your Lordships. The bit that achieved most publicity and notoriety at the time was our policy on the nuclear deterrent. I am tasked this evening with advocating that again, so I think I will be the only Member of your Lordships’ House this evening not saying that I support the Government I will say in advance that, while I am speaking officially in terms of the party line, my own view is very much as a multilateralist. Certainly, anything that I am saying should not be taken as suggesting in any way that I am advocating a unilateralist position, nor indeed that my party is advocating a unilateralist position. I will explain shortly because I can see quizzical faces There have been suggestions from various Members of your Lordships’ House that this is a snap decision, and it has been asked why we are making it now. We are not making a snap decision this evening. We have been talking about this for at least 10 years. The Liberal Democrats are now on, I think, our fourth review of what we think our policy should be. Back in 2006-07, the policy review was led by the late Lord Roper and the person responsible for drafting the then policy was the late Lord Garden, both of whom reviewed and took this issue extremely seriously. I was on that working group. At the time, a decade ago, we were reviewing whether it made sense to have an independent nuclear deterrent. The words of Sir Michael Quinlan, which have been mentioned by various noble Lords this evening, were important. Was it still the appropriate measure to have after the end of the Cold War, in a world where the threats seemed to be changing and the threat of Russia was perhaps less significant than it had been Clearly, the situation now is very different. Russia now poses a threat, and the only nuclear threat that seems to have abated in the past decade is that of Iran. The geopolitical situation a decade on is such that those of us who had questioned whether a nuclear deterrent that arose during the Cold War was still appropriate in the 21st century have begun to change our minds The position that my party took in 2007 was to say very clearly that the decision on a replacement for Trident did not need to be taken then. The main-gate decision did not need to be taken until the 2010-15 Parliament. For reasons that we do not need to rehearse now, that decision was not taken until 2016. The Liberal Democrat position is that we believe we should retain a nuclear capability. We believe the threats are such that the United Kingdom and her European allies need to have a nuclear deterrent, but we do not believe in like-for-like replacement. The noble Lord, Lord West of Spithead, might suggest that we are closet unilateralists The party’s position was debated at great length over the years and agreed in 2013: that we believed in retaining a nuclear deterrent but we were not persuaded that it was essential to keep a four-boat solution. While I understand that that is not going to work—were we to have a vote this evening, I would be in a minority, possibly of two, because I note that my Chief Whip has appeared and would support this line as well. But the position that the Liberal Democrats took, after a prolonged debate, eschewed the unilateralist perspective that many in my party, like the leader of the Labour Party—his position was outlined earlier by the noble Lord, Lord Tunnicliffe—would have preferred My party was willing to accept the retention of nuclear weapons and the replacement of Trident, but not like-for-like replacement, on the understanding that we would seek to take a step down the nuclear ladder, and that giving up nuclear weapons in a unilateralist way—saying simply, "We no longer wish to retain nuclear weapons"—would not give us any leverage in non-proliferation discussions. Keeping a seat at the table was important, and having a non-like-for-like replacement would at least ensure that we were still building submarines, retaining the skills that, as we have heard, are so important for our economy but also for the country’s nuclear capability. Therefore, while moving away from continuous at-sea deterrence might strike some of your Lordships as leaving us vulnerable, it would also mean that we have not lost such capability and that we keep many options open, in a way that a step to unilateralism would not. The official Liberal Democrat position is that we do not support the like-for-like replacement of Trident but we do support the retention of nuclear capabilities and believe that stepping down the nuclear ladder would pave the way for further discussions on non-proliferation I will conclude with two questions for the Minister. First, in light of questions about non-proliferation, can he explain how the Government intend to contribute further to non-proliferation discussions once a decision on the four-boat solution is voted on next Monday? We have five-yearly reviews of the non-proliferation treaty. They tend to coincide with general election years, which perhaps has meant that the United Kingdom has not played as significant a role in the discussions as it might have. What scope might there be in 2020 for a key British role—
