Trident

Debate between Philip Dunne and Jonathan Reynolds

Tuesday 24th November 2015 Commons Chamber

[The Minister for Defence Procurement (Mr Philip Dunne)]

I am pleased to be able to follow the hon. Member for East Renfrewshire (Kirsten Oswald). I believe that she was making her debut in winding up a debate on behalf of her party, and I congratulate her on that. As she said, this has been a well-informed and at times passionate debate, and rightly so, because the strategic deterrent forms a key part of the Government’s No. 1 priority: the defence of the realm.

The Government are committed to maintaining a minimum credible and assured deterrent, as was clearly stated in the manifesto on which they were elected to govern the whole of the United Kingdom. The hon. Lady argued that we should respect the wishes of the Scottish people, and we should indeed take them into account, but that is the same argument as was advanced by the then leader of the Greater London Council when he declared London to be a nuclear-free zone. No nuclear weapon would have been allowed in this country had his views been entirely respected. That is not an argument that we can respect, because we have responsibility for the government of the United Kingdom as a whole.

We are committed to building four new nuclear-armed submarines to replace the current four Vanguard class submarines, but not to replacing the Trident missile, which is the notional subject of the debate. As was pointed out by the hon. Member for Chesterfield (Toby Perkins), the subject of the debate is not, strictly speaking, what is at stake today, because what we are actually discussing is whether or not to replace the submarine class, rather than the missile system.

Why do we stand by our commitment? First, as the Secretary of State said, this is about being realistic. We do not live in an ideal world, much as we might wish to. Our deterrent is there to deter the most extreme threats to our national security and way of life. Those threats have not gone away, however much people might wish it were otherwise. The national security review which was published yesterday shows that, if anything, they are growing and becoming more complex and more diverse by the day.

Under the coalition Government, we as a nation took steps to reduce nuclear arsenals, and we have reduced the number of deployed warheads on each submarine from 48 to 40. Other nations with nuclear weapons have not responded to that unilateral action. They need to follow our example, and nations without nuclear weapons should end all notions of obtaining them. Those who wish to gamble with the nation’s security do so with no ability to predict what the world might be like in decades to come.

[Jonathan Reynolds (Stalybridge and Hyde) (Lab/Co-op)]

Will the Minister give way?

[Mr Dunne]

I am afraid that I have very little time.

Secondly, our deterrent works for us every day, for 365 days and nights each year, thanks to the brave service of so many of our valiant personnel serving on the Vanguard class submarines—and, indeed, the husband of the hon. Member for Glasgow North West (Carol Monaghan), whom she mentioned earlier. I believe that he has now retired from the Royal Navy, but I respect the service that he gave.

The fact that we have a continuous at-sea deterrent sows the seeds of doubt in the minds of our potential adversaries. As was emphasised by my hon. Friend the Member for Tonbridge and Malling (Tom Tugendhat) in a powerful speech, continuous at-sea deterrence works because it provides the ability to strike back. It also provides another decision-making centre in the NATO alliance, and complicates and confuses an enemy’s calculations.

Finally, there is no alternative. Notwithstanding the recollection of my friend and former colleague the right hon. Member for Orkney and Shetland (Mr Carmichael), the 2013 Trident Alternatives Review made it very clear that if we were to have a cost-effective way of delivering the minimum nuclear deterrent, Successor was the only viable solution. Moreover, the ramifications of removing our deterrent would be immense, putting at risk not just our national security and our position in NATO—the cornerstone of our defence—but our economy, our essential skills base, and thousands of jobs across the United Kingdom.
