From the Telegraph this morning (before the ruling):
“The case comes as counter-terrorism chiefs are braced to face down a renewed threat from extremists who, like Ms Begum, have travelled, or plan to travel, overseas to join militant groups. Matt Jukes, the head of counter-terrorism policing, said an increasing number of jihadists were being detected travelling to countries such as Syria, several years after IS lost its grip on the region.
Islamist terrorism is still considered to be the greatest threat to the British public, according to the police chief.
Authorities fear that if Ms Begum were to win the case, it could set a precedent that allows an influx of potentially dangerous jihadists. It has been estimated that around 60 British citizens are being held in indefinite detention in Syria after fleeing areas once controlled by IS. A greater threat could be posed by up to 150 terror suspects who have been stripped of their British citizenship and could try to challenge their own rulings if Ms Begum’s case succeeds.”
