I must make some progress, if my hon. Friend will excuse me.
The second speech by which I was considerably influenced was that of the hon. Member for Penrith and The Border, who talked in realistic terms about resources, in particular the resources available to the Foreign Office. I would like to say a few words about the resources available to the three security services, which as it happens are giving evidence to the Intelligence and Security Committee today.
If the threat is increasing and if the analysis is that there is a greater risk of terrorist activity in this country as a result of returning jihadists, one way to begin to seek to meet that threat is by ensuring that those who are on the front line of seeking to disturb or prevent such actions from taking place are properly resourced. That means investing money—and, yes, it means taking money away from other things. We should never forget that the primary duty of any Government is the defence and the security of their own citizens.
