Shamima Begum has lost an appeal against the revocation of her British citizenship, after MI5 argued that she continued to pose a threat to national security.

Ms Begum, now 23, fled the UK at the age of 15 to join the Islamic State (IS) terror group in Syria and had her British citizenship removed by the Home Secretary when she resurfaced in a refugee camp in 2019. 

She mounted a legal challenge against the decision, arguing that MI5 was wrong to conclude she represents a threat to the British public and claiming she was trafficked to Syria for sexual exploitation. 

On Wednesday, Mr Justice Jay, sitting at the Special Immigration Appeals Commission (SIAC), rejected Ms Begum’s legal challenge.
