Dr Julian Lewis: For understandable reasons, Defence spending has more than halved as a proportion of GDP since the end of the Cold War. Now that the threat from Russia is re-emerging, can we reassess the need to fill the holes in the Defence budget identified by the National Audit Office, the Defence Committee, and, most recently, the Joint Committee on the National Security Strategy?

As he ​will know, coming out of the National Security Capability Review, we have set out the Modernising Defence Programme. We are looking carefully at the question of our future defence against the background of the threats that we face.
