I am grateful to my right hon. Friend for that. These figures seem extraordinarily large to us, but if we consider the worst coming to the worst, and our being in a hot war in Europe, we would be back to spending significantly more. It was 50% of GDP in world war two, so the figures we are talking about are essentially marginal in light of the potential.
The point has been made—it cannot be made enough—that before defence gets more money, it needs to spend its own money better. I echo the points made about the importance of procurement reform. The Public Accounts Committee report is damning. There is a £17 billion deficit between the MOD’s budget and its official capability requirements, which is perhaps an underestimate, as my right hon. Friend the Member for Rayleigh and Wickford said, given how these numbers are calculated. I am concerned about that.
To make a quick point in passing, I would be interested in the Minister’s thoughts when he winds up about the nuclear budget. There is real concern about how Trident’s replacement will be accounted for. There is a danger that if that is just part of general MOD capital expenditure, it could end up cannibalising conventional weapons. It is important, given the long-standing tradition, that we keep nuclear separate from conventional weapons budgets.
