[Mr Speaker: Let us go to another expert – Dr Julian Lewis.]
Dr Julian Lewis: Does my right hon. Friend accept that while the cyber-threat to critical national infrastructure can paralyse a society that is then subject to attack by more conventional means, we also have to maintain the methods and equipment to counter-attack anything involving conventional military force? Is he satisfied that the integrated review, while recognising the role of cyber, also recognises the continuing role of conventional defence?
[The Secretary of State for Defence (Mr Ben Wallace): My right hon. Friend makes a valid point; we absolutely recognise that. The important thing about the Command Paper and the integrated review is learning the lessons of today. The lesson that we learned from Syria was that when we tackle Daesh, we tackle its cyber-offence and cyber-campaign in tandem with the military campaign that we used to take apart its leadership and the evil tasks that it was setting out to cause attacks. It is absolutely the case that there cannot be one without the other, but we should also recognise that the growing vulnerability of our forces and civil society to cyber as we become more dependent on cyber means that we have to take a very strong lead in defending against that.]
