I am so pleased that the hon. Gentleman has raised this very significant milestone and also given us the opportunity to thank all those who have served, for coming up to 50 years, in protecting our United Kingdom around the world from, as he says, the threat of nuclear blackmail. When I was 13, it was the risk of a nuclear war that made me decide that I was going to become a Member of Parliament, so this very issue has been with me for an extremely long time—longer than I care to think of. I will certainly take his request very seriously and see whether we can find Government time, but I am very glad to hear that he has already got his request in to the Backbench Business Committee.
