Yes, and I will come to the issue of how we can use the percentage of GDP to track what has been happening to defence in a moment. I hope that the hon. Gentleman—a former Defence Minister in the Labour Government, of course, and a very good one—will try to be non-partisan about this for the simple reason that successive Governments are responsible for what has happened.
What actually took place was, as has already been hinted at, something that has been going on over a very long period. Colleagues on both sides of the House have heard me recite this so often that I am afraid they might do that terrible thing and join in, singing the song with me. But I will just run through it again. In 1963, the falling graph of defence expenditure as a proportion of GDP crossed over with the rising graph of expenditure on welfare at 6%. So we were spending the same on welfare and defence—6%—in 1963. In the mid-1980s, as we have heard, we regularly spent between 4.5% and 5% of GDP on defence, and that was the period when we last had an assertive Russia combined with a major terrorist threat—the threat in Northern Ireland. We were spending at that time roughly the same amount on education and health. Nowadays we spend six times on welfare what we spend on defence, we spend four times on health what we spend on defence, and we spend two and a half times on education what we spend on defence.
We have to ask what we mean when we say that defence is the first duty of Government. If it is the first duty of Government, it is a duty that is more important than any other duty, because if we fail to discharge it everything else is put in jeopardy.
