The former Attorney General Dominic Grieve appeared on Radio 4’s World at One Today to discuss the government’s new plan to “regulate” the return to the UK of those who, for instance, have gone to Syria to fight for the “Islamic State”.

Grieve said his impression was that the new proposals – announced by the Prime Minister overnight in a speech to the Australian Parliament – do not seem aimed at “banning” UK citizens from returning to the UK, which they have a legal right to do, and which would risk breaching international law by making them stateless.

My understanding of the proposals is the same as Grieve’s: the plan is to force people to arrange their return to the UK with British authorities, rather than in any sense to “ban” them from coming back. On that basis, I think there’s a good chance the new regime would be legally defensible.
