Continuous At-Sea Deterrent

Alex Chalk Excerpts

Wednesday 10th April 2019 Commons Chamber

[Gavin Williamson]

I thank the hon. Gentleman for his intervention. I will deal with it and then make some progress, because there is a lot of interest in the House and many hon. Members want to speak. The hon. Gentleman raises an important point, and it is why the Government have set aside £31 billion to deliver the Dreadnought programme and ensure that we have continuous at-sea nuclear deterrence. We have also built in a contingency, because we are very conscious that we want to provide security confidence that the programme will deliver within budget and on time.

It is important that we pay our thanks to those who have served on the submarines, to families and to the whole industry. Next month, there will be the Westminster Abbey service recognising the commitment of our submariners. In July, there will be a parade at Her Majesty’s Naval Base Clyde, and at the end of the November, there will be a special memorial commemoration at Edinburgh Castle.

However, today’s debate is important because it gives us the opportunity to underline why the deterrent still matters so much to the United Kingdom, why it remains very much at the heart of our national security policy and why it has been one of the rare issues to command popular support across both sides of the House. It is an important point to make that the continuous at-sea deterrent has been supported by both Conservative and Labour Governments continuously over the last few decades; I certainly hope that it will be for many decades into the future.

The doubters who persist in believing that the deterrent is simply a cold war relic need to be reminded of three salient points. First and foremost, the nuclear dangers have not gone away; on the contrary, the geopolitical situation is more unstable than ever before. We are facing challenges that are growing in scale, complexity and diversity. Russia is rebuilding its nuclear arsenal. It has breached the intermediate-range nuclear forces treaty and, in Europe, has now deployed new nuclear-capable missile systems to target and threaten the west. It also continues to develop and adapt its doctrine to give primacy to nuclear weapons. North Korea is the only state to have detonated a nuclear weapon in the 21st century. Despite positive dialogue, its weapons remain intact. We hope it will return to compliance with its obligations under the non-proliferation treaty. The point is that both Russia and North Korea have shown their willingness to rattle the nuclear sabre in the past.

There are no indications that those dangers will disappear any time soon, so we cannot relax our guard. While there is the risk of other states developing weapons, we must have a credible response to that threat. Our independent nuclear deterrent—our nuclear weapons posture—gives us defences against such actions. It is our ultimate insurance policy. It protects us every day from the most extreme threats to our national security and our way of life. Beyond that, it gives future generations greater strategic options and the power to protect themselves into the 2060s and beyond, whatever may lie round the corner.

As was recognised at last year’s NATO summit in Brussels, the UK’s nuclear deterrent provides a critical contribution to our alliance. Since 1962, the UK has assigned all our nuclear forces to NATO’s defence. That 50-year commitment to the defence and security of every member of that great alliance is as strong today as it has ever been in the past. All member states benefit from that capability, which gives the alliance another centre of decision making to complicate the calculations of our adversaries.

In fact, many allies signed the non-proliferation treaty in the late 1960s safe in knowledge they would be covered by the nuclear umbrella that the United Kingdom provides for them. Those who argue that we should disarm should consider whether such a move would actually make nuclear proliferation more, rather than less, likely. We cannot blame others, such as the United States, for questioning why they should be paying the price for protecting us from nuclear threats.

My constituency is the home of GCHQ, which has unprecedented and unparalleled security co-operation and intelligence sharing with the United States. Does the Secretary of State agree that the UK’s commitment to the continuous at-sea nuclear deterrent is one of the foundation stones of that strong relationship, which keeps our people safe?

[Gavin Williamson]

My hon. Friend makes an important point, which I will touch on later. Our nuclear deterrent is a cornerstone of that long and enduring relationship. The United States does not have such a relationship with another country anywhere on this Earth. That close collaboration makes us and our allies safer.
