Of course, my hon. Friend loses no opportunity to stand up for Plymouth, but let me say, as Prime Minister, how much I welcome the fact that we bring to our armed forces those from every part of the United Kingdom. We can think of the magnificent service of the Scottish regiments and the expertise of those who have built our incredible warships in Scotland—most recently, of course, the aircraft carriers. It is the contribution of all parts of the United Kingdom that means we have a defence budget that is one of the top five in the world and armed forces that are the envy of the world. My argument would be not just that Scotland benefits from being part of that but that it contributes a huge amount to what is a unique asset around the world.
