My Lords, I am glad that the Government are not complacent. I am sure that the House generally will share that view. It may also share the view that some further action to demonstrate that lack of complacency would not be unwelcome.

I recall an interview that I had with Mr Attlee in the demobilisation period in 1947. He said that the view that I expressed, which was that nuclear weapons had to be got rid of, had been shared at an even "higher level"—as he put it, pulling my leg. The higher level concerned was the supremo himself, Lord Mountbatten. It was his view that we must get rid of this damn thing quickly or the damn thing will get rid of us. We have been spared that, although it has sometimes been a close-run thing. But we must not be complacent. I suggest that the Government should be called on to demonstrate that lack of complacency more fully than they have done hitherto.
