My right hon. Friend is painting a picture of the complexity and severity of the challenges we face. That threat has changed over the years, to the point at which the level of skill required across a broad range of disciplines is growing. I was fortunate enough to be the envoy for the year of engineering last year and saw how our armed services use engineers both on the ground and behind the scenes to tackle some of those threats, particularly on cyber-security. Will he therefore join me in promoting engineering within the armed services as a way of meeting and tackling the challenges that he is talking about?
