Every week, I see cases of exclusions. We exclude people in line with the legislation. If they are from the EU, we have some powers to exclude, and if they are from outside the EEA, we have more powers to exclude. We exclude people and, as I said, deprive people of their citizenship where the intelligence evidence points to the fact that either there is no alternative or they pose a considerable threat.
The biggest challenge for the future is safe spaces—people’s ability to communicate through end-to-end encryption, go online or go to a warzone such as north Syria, where they can play a part in planning and directing attacks. We, as a country, have very little reach into those places, either to affect behaviour or indeed get justice delivered. One of the biggest challenges in this case is that the detention of these individuals is not by a state; it is by a non-state actor in a prison in north Syria, which is a warzone. That is a real barrier to what we can do in the pursuit of justice for the victims of the crimes that these people are accused of.
