Shamima Begum has lost her latest bid to regain British citizenship as Court of Appeal judges ruled the government was entitled to banish her to protect national security.
The former East London schoolgirl left the UK and travelled to ISIS-controlled Syria in 2015, when she was 15-years-old, and her citizenship was revoked four years later when she turned up in a Syrian refugee camp.
Begum married a jihadi fighter and gave birth to three of his children during her time with the terrorist group, and now argues she was a victim of trafficking who was exploited as a teenager when she left the UK.
Last year the Special Immigration Appeals Commission (SIAC) rejected her bid to regain British citizenship, and Court of Appeal judges on Friday upheld that decision.
