Trident

Debate between Alistair Carmichael and Lord Walney

Tuesday 24th November 2015 Commons Chamber

[Mr Carmichael]

I am not responsible for every contribution from every member of my party in every constituency, any more, I suspect, than the hon. Lady would want to be for her own party. I will come to my party’s position in a moment, because I think it is central to the debate and I want to put it on record. The hon. Lady has the advantage of being able to consider the terms of the amendment that was tabled but unfortunately was not selected for Division today.

It is worth remembering that we are having this debate only because the maingate decision, which was to have been taken in the previous Parliament, was delayed until this Parliament. When the Minister responds to the debate, I invite him to accept that although his party wanted to take that maingate decision in the last Parliament, events vindicate the decision that was made and this is the right point in the cycle to take it.

We live in an ever-changing and uncertain world. As the hon. Member for Elmet and Rothwell (Alec Shelbrooke), I think, said earlier, we cannot ignore the fact that nuclear weapons exist. I wish they could be uninvented, but they cannot. That is the basis on which we should approach this debate. It is not just about whether the position should be reviewed or not: it is about what the United Kingdom, as a permanent member of the United Nations Security Council, can do to take a lead in the international community and among the nuclear powers to ensure that there is a serious movement towards multilateral nuclear disarmament.

This was a formative debate in my early political years, as it probably was for you, Madam Deputy Speaker, in the 1987 general election, but the world was a very different place in 1987. The cold war was still at its height and the Soviet Union still existed. We have seen enormous change since that time, but the change has not all been in one direction. We have only to look at the situation in Ukraine and Crimea to realise that such old enmities never die. It is not pertinent to say what is a tier 1 or a tier 2 risk at this point. The question is what the situation will be in the future.

Having said all that, I would still say that the Government’s determination to pursue a like-for-like replacement for Trident ignores the different world in which we now live and misses the opportunity that we have as a force for multilateral nuclear disarmament to take a different approach—to take a step down the nuclear ladder—and as a nuclear power to meet our obligations under the various nuclear non-proliferation treaties.

When the Secretary of State addressed the House, he spoke of what he has done to reduce the number of nuclear warheads currently available for deployment. I commend him for that. He lamented the fact that this has elicited little response from other nuclear or nuclear-aspirant countries. I suspect that that is because despite the reduction in the number of warheads, the Government continue to cleave to the notion of continuous at-sea deterrence. The time has now come for a very long and serious look at whether that remains an appropriate approach. My party has reached the conclusion that it is no longer necessary or appropriate. We would like to see an end to continuous at-sea nuclear deterrence, while of course maintaining our deterrence capability. That would allow us to take something of a lead in taking the step down—[Interruption.] If the hon. Member for Barrow and Furness (John Woodcock) wishes to intervene, I will take an intervention, but I will not take sedentary chuntering.

[John Woodcock]

My hon. Friends and I are baffled about how this part-time deterrence would work. Why would it save money, how would it stop the first-strike capability, and what would the submarines do when they were not deterring?

[Mr Carmichael]

If the hon. Gentleman wishes to have a serious debate about this, then I am well in the market for that. He should understand, though, that this is a legitimate and substantial proposal that commands a lot of support among many people who understand and accept the need for nuclear weaponry but are prepared to look at how we use our position as a nuclear power and as a proponent of nuclear disarmament rather than as something that is—[Interruption.] Before he continues to shake his head, he might well find that his own party’s review comes up with something very similar to this. He should be careful not to disparage today what he might find in his manifesto tomorrow.

It is unfortunate that this debate has occasionally generated more heat than light, but it is an important one that this House has to have, and I suspect that we shall be returning to it in the months and years to come. When we do so, it should be on the basis that this is our opportunity to be a leading force for nuclear disarmament in the world; it is not all just about the renewal of weaponry.
