Nuclear Deterrent

Sheryll Murray Excerpts

Thursday 17th January 2013 Commons Chamber

[Sheryll Murray (South East Cornwall) (Con)]

I start by thanking my hon. Friend the Member for New Forest East (Dr Lewis), the hon. Member for Newport West (Paul Flynn) and the Backbench Business Committee for ensuring that we have this important debate today. Members will know of my special interest in the Royal Navy, as the mother of a serving Royal Naval officer, although my daughter assures me that she has no desire to serve aboard one of the four Vanguard class submarines.

I am pleased that the Government are committed to maintaining the UK’s nuclear deterrent. The Government have also approved the initial gate investment, and selected the submarine design for the successor nuclear deterrent. Contracts have been signed for the first 18 months of work on the assessment phase of the successor submarine programme.

Trident has provided a massive amount of employment for my constituents in South East Cornwall. Repair, refuelling and refit of the Vanguard class submarines is carried out in the D154 submarine support facilities at Devonport. The expertise and experience that Devonport now has should be utilised in any future programme. As a local county councillor at the time, I will never forget standing by the banks of the River Tamar in Mount Edgcumbe park, and watching the first Vanguard submarine edge her way around Drake’s island and into Devonport dockyard for refit. I was pleased that my right hon. Friend the Secretary of State announced that the £350 million contract to refit and refuel the nuclear missile submarine HMS Vengeance had been awarded to Devonport in March last year. It will safeguard up to 2,000 jobs.

[Oliver Colvile (Plymouth, Sutton and Devonport) (Con)]

Does my hon. Friend accept that that is also an important part of our skills base, and that if it were to go, we would see a significant diminution in our skills base?

[Sheryll Murray]

My hon. Friend is right.

Maintaining a continuous at-sea deterrent is essential. It sends the positive message that the UK is always prepared to respond instantly. There is the additional advantage of a moveable location, which assists security against any possible threats. The Government have excellent principles to abide by when considering nuclear arms. These include the use of nuclear weapons only in extreme circumstances of self-defence, a commitment to a minimum nuclear deterrent, and not to use any weapons contrary to international law. In other words, the highly powerful weapons would be used only as a last resort.

It is important to retain nuclear weapons. I was concerned at our going into coalition with partners who stated in their last election manifesto that they would be saying no to like-for-like replacement of the Trident nuclear weapons system. Given the reports in The Independent on 19 July last year, I am still concerned that they might scale down our vital nuclear deterrent in increasingly uncertain times.

We need to remember that the UK’s nuclear deterrent contributes towards our collective security as part of NATO. If the UK did not have an at-sea deterrent, NATO’s collective security would be weakened, leaving the UK dependent on the US and France.

[Damian Collins (Folkestone and Hythe) (Con)]

Does my hon. Friend agree that major wars tend to start when dictators believe that democracies are too weak to stand up to them? For democracies such as Britain to give up their nuclear deterrent would send out entirely the wrong message about how we seek to protect others and ourselves.

[Sheryll Murray]

That is exactly true.

The UK has a permanent seat on the UN Security Council. We were awarded that position because our nation was one of the most powerful in the world following world war two. The UK’s membership of that exclusive club could be called into question without the continuation of our nuclear deterrent.

A British at-sea nuclear deterrent has served us well for 60 years; it can and should serve us well into the future. I hope that refitting work on any future submarines will continue to provide much-needed employment opportunities for my constituents in Saltash, Torpoint and throughout the rest of South East Cornwall.

--- Later in debate ---

[John Woodcock]

The hon. Gentleman is absolutely right. Most of all, such cruise missiles are indistinguishable on an enemy radar from conventional cruise missiles, raising the chilling prospect that in the confusion of battle, a conventional attack by the UK could trigger nuclear retaliation against British cities.

[Sheryll Murray]

Does the hon. Gentleman agree that if we took up this idea, we could see another tuition fees scenario?

[John Woodcock]

I certainly know what the hon. Lady means—I am reluctant to compare tuition fees to the ultimate deterrent, but in political terms she is absolutely right.

To those looking to the latest review into the future of the deterrent and hoping that a major—and needed—push on global non-proliferation could make it possible for the UK effectively to wait and see before committing to renew, I put two questions. First, is it really realistic to expect a breakthrough within the next few years in global security—involving not just the former Soviet Union and America, but the whole world—that would give us sufficient hope that a hostile nuclear power could not plausibly threaten the United Kingdom 20, 30 or 40 years hence? That is the judgment that we have to make now. Secondly, what would be the industrial and financial consequences of a further delay, on top of the already significant increase in cost caused by the coalition Government’s delay, which enabled them to kick the main gate decision on a successor into the next Parliament?

Industrially, we must think in terms of jobs now and over coming decades. Let us not forget that we are talking not just about 5,000 or 6,000 jobs in Barrow shipyard, critical to the regional economy though they are, but about the 4,000 jobs and rising in the nuclear submarine supply chain, stretching right across the country. We must also consider the UK’s prized capacity to manufacture submarines of any kind. We rightly say that, for security reasons, we should not procure from abroad, but if we leave another gap in production like the one in the 1990s—the Astute programme is still suffering from the attempt to recover from that—we could lose those highly honed skills from these shores for ever.

Of course we should always examine new evidence, but so far all credible evidence has pointed to the same place: that like-for-like renewal is the most effective—and the most cost-effective—way of maintaining the UK’s minimum independent deterrent and that the decision to renew should be kept at arm’s length from our profound moral obligation to pursue a world free from the threat of nuclear war.
