I am grateful to you, Madam Deputy Speaker, for allowing me to contribute to the debate.

I represent the great city of Plymouth, where we have a long and proud naval history. Plymouth is where the Vanguard-class submarines are repaired and refitted. I will not make an overly lengthy contribution today, but I would like to give my experience of the representations made in my constituency, where the Trident programme plays such a significant role in our local economy. Representatives of Plymouth, sent here to represent our famous naval city, have always taken very seriously our twin responsibilities—to the nation’s security and to the employment prospects of those who have loyally maintained, and continue to maintain, the submarines that carry Trident missiles.

The Vanguard submarines are repaired and refitted at the Devonport dockyard in Plymouth. For me and my colleagues who represent Plymouth, they are a vital source of employment for thousands, as they are for other Members with naval bases in their constituencies. That source is not as easily replaced as some might think, and my colleagues’ view and mine is that it would be simply a gamble too far. We live in a desperately unstable world. Last weekend was perhaps the most unstable for years. That should not in itself be an argument for maintaining our Trident programme, but it illustrates how we simply cannot predict events beyond next week, let alone far in the future.

National security is fundamental to delivering all that we come into politics to deliver—a fairer society, social justice and opportunities for all. Without it, none of the causes that I know I share with many Opposition Members would be achievable. The Government have a responsibility to put the security of the nation and its people first and foremost. We need to maintain our ultimate deterrent, because we simply do not know what the future holds.

I am not deaf to those concerned about the costs and risks of maintaining the fleet in Plymouth. There is an active community of people who write to me often about that issue. As with any other contentious issue, I have sought to understand the arguments. I speak to those who agree with me and, more importantly, to those who disagree with me. On this issue, however, I am single-mindedly sure: we must maintain our commitment to this programme and replace the Vanguard-class submarines with the new Successor class. Strategically, we cannot and should not wear the risk that comes with abandoning our continuous at-sea deterrence, and the message that that would send to our NATO allies.
