Counter-Terrorism and Security Bill

Is not one potential problem with the right hon. Gentleman’s proposal, which is in many ways perfectly reasonable in structure, that it does not prevent the individual from continuing to travel abroad between third countries? If the UK Government reasonably suspect that somebody is involved in terrorism, ensuring that person’s managed return—an act of a responsible Government—to this country is perhaps a priority. Is there not a danger that the right hon. Gentleman’s proposal would enable such a person to continue using their passport abroad, because the carrier would have no responsibility to give notification of travel between different countries?
