Counter-Terrorism and Border Security Bill

I congratulate the Minister and the Government for—although belatedly—bringing in this power, for which I and many others have long been calling. It was patently obvious that many of the Brits who we knew were travelling to Iraq and Syria had no other reason to be there than to support terror, but there was not sufficient evidence to prosecute, hence 400 of them, by the Government’s own estimate, are coming back largely without prosecution. Do the Government have an estimate of how many of those 800 Brits who we know went over to Raqqa during the recent conflict could have been prosecuted under this legislation, had it been on the statute book at the time?
