I thank the hon. Gentleman for his good wishes for the final stages of this renegotiation. This will be a big argument in the campaign. Like many on this side of the House, I have always seen NATO as the cornerstone of our defence, but as I said earlier, in the modern networked world the work we do, for instance in the Mediterranean to try and stop people leaving Libya and making the perilous journey to Italy, could be a NATO operation but right now it is a European operation in which Britain is playing a leading part. Being a member of networks where we can work together for our security is important.
