I thank my right hon. Friend for giving way, and it is a pleasure to serve under his stout chairmanship of the Defence Committee—[Interruption.] I mean stout in personality terms.
In some ways, the situation is even more challenging than the one my right hon. Friend lays out. He has rightly given the figures in terms of GDP, but in recent years—as we heard in testimony from the permanent under-secretary—in almost every strategic defence and security review and comprehensive spending review, the MOD has had to sign up to additional sets of efficiency savings, now totalling some £30 billion over time. Not only does the MOD have a constricted budget, it has had to find those efficiency savings as well, which makes the situation even more challenging.
