David Cameron has outlined plans to give police and security services extra powers to use against Britons suspected of joining Isis (the Islamic State).
It is thought at least 500 Britons have travelled to Iraq and Syria to join jihadists who earlier this year set up a self-declared Caliphate and have been accused of a succession of atrocities against non-Sunni Muslims and minority groups.
The terror law proposals broadly fall into two categories:
What is proposed?
Giving police the power to seize passports of suspected terrorists. The Home Secretary already has that authority. Extending it should prevent more jihadists heading to war zones.
How it would work?
Police could only confiscate passports temporarily while they investigate an individual's background.
Will it happen?
The move is supported across parties and legislation is planned in case an ongoing legal challenge succeeds.
A "targeted, discretionary" power to stop British nationals suspected of involvement in terrorism from returning to the UK.
Mr Cameron was extremely vague on any details, simply saying: "We will work up proposals on this basis with our agencies."
Unlikely, given the weight of practical problems.
