The hon. Lady makes an important point, given our relationship with the Republic of Ireland and the operation of the common travel area. I can assure her that we work very closely with the Irish Government on the necessary information exchange between us, to ensure that the common travel area could not be—and, in general, is not—a means by which people can access the UK when we do not wish them to do so.
As I was saying, this is a necessary and proportionate power and, given the circumstances in which we find ourselves, it is entirely appropriate to introduce a power that will enable us to disrupt and mange the return of a number of individuals who have been involved in terrorist-related activity outside the UK.
