The hon. Gentleman is absolutely right to raise that point about cyber-attacks. Crucially, very few of us in this House—I certainly include myself in this—understand cyber in detail. We are taking it on faith that we are developing a significant cyber-capacity. It is extremely difficult for us to be confident about what we are doing in this regard. I have two questions on cyber that I would like to put to the Minister. One is to do with NATO’s cyber-capacity. The members of the Committee visited the cyber-centre in Estonia and discovered that there were only two UK personnel posted to that site. It was very difficult to be confident about what deterrent effect that kind of cyber would involve.
My second question is to do with doctrine. Are we prepared to threaten a cyber response as a way of deterring a Russian cyber-attack? In other words, if Russia were to mount a cyber-attack against a NATO member state, would we respond with a cyber-attack in kind?
