I might be a touch over-optimistic, but I get the impression that a sea change is going on, at least in this Chamber. It was only in 2016 that we first started to debate whether 2% of gross domestic product was a sufficient investment for this country to make in defence in peacetime. At that time, it seemed fairly outlandish to suggest that we ought to be talking about 3% of GDP or even more. It is not outlandish to suggest that now. Of course, that is partly because of the shift in the strategic situation, which my right hon. Friend the Member for Rayleigh and Wickford (Mr Francois) outlined so comprehensively a few moments ago, but it is also partly because of the efforts of colleagues on the Government and Opposition Benches—I pay tribute to my old friend, my hon. Friend the Member for Gainsborough (Sir Edward Leigh), for doing this today—to bring this subject forward time and again to impress on the House and the country that we are simply not investing enough in defence.
My right hon. Friend the Member for Rayleigh and Wickford referred to pinstriped warriors in the civil service. I do not wish to point any fingers in any particular directions, but when the National Security Adviser appeared before the Joint Committee on the National Security Strategy on 18 December and was asked whether it would be possible for him to recommend that the defence budget ought to be increased, given the fact that the security capability review that he had been conducting was supposed to be fiscally neutral, it worried me that he responded:
“When I said that the 2015 review was fiscally neutral, it was fiscally neutral within a growing envelope.”
In other words, he meant that there were certain absolute increases in the sums being spent. At a later stage, having tried to lump together the defence budget with all other moneys spent on security of one form or another to give a global figure of £56 billion, he went on to say:
“If we concluded that the total set of capabilities, optimised across that £56 billion, was insufficient to meet the threats, of course we would say that to Ministers. That is not a conclusion I expect to reach, but of course I always have the freedom to give Ministers candid advice.”
I am rather worried if our top security professionals do not feel even a twinge of doubt about the level of priority that we are giving to defence. When sometimes people stress the point, which is not without merit, that when we talk about spending 2% or 3% of GDP we are talking about inputs, not outputs in terms of capability, I say to them that of course it is true that we could spend a huge amount of money on defence, but if we spent it on all the wrong things, it would not do us a lot of good. Conversely, though, if we are simply not spending enough on defence, nothing that we can do will give us the outputs we need.
