What the hon. Lady is saying about the Royal Navy is music to my ears. I look forward to participating in the armed forces scheme next year.

The F-35 is a splendid aircraft that I fully support us buying from the Americans, but the bitter fact is that, as we all know, we will never own all the intellectual property of that aircraft. We will never know exactly how it works because of security aspects. Why should the Americans tell us? That is one reason why keeping manufacture here in the British Isles as much as we can is crucial. Only if we make it, or do so in partnership with others, will we know everything there is to know, with that information being secure.
