I absolutely understand my hon. Friend’s point. He has pointed out, quite correctly, the challenges of prosecution of foreign terrorist fighters who return to the UK. As we have heard from my right hon. Friend Dr Lewis, one challenge is having the right laws in place—we are making some changes to that—and another is collecting battlefield evidence. These individuals are returning from a war zone. Collecting evidence in the battlefield is incredibly difficult, but we have done, and continue to do, a lot of work through the MOD and with our defence allies and Five Eyes partners to try collect more such evidence, so that we can use it in the courts for more successful prosecutions.
