Shamima Begum has lost her legal challenge over the decision to deprive her of her British citizenship.
Ms Begum was 15 when she and two other east London schoolgirls travelled to Syria to join the so-called Islamic State (IS) in February 2015.
Her British citizenship was revoked on national security grounds by then-home secretary Sajid Javid shortly after she was found, nine months pregnant, in a Syrian refugee camp in February 2019.
