Shamima Begum – the teenager who fled London to join Islamic State in Syria – has said being stripped of her British citizenship is “unjust”.
Ms Begum, 19, told ITV News that she found the Home Office’s decision “heartbreaking”, but she may try for citizenship via her Dutch husband.
Her family have said they plan to challenge the government’s decision.
Government sources said it was possible to revoke her UK nationality as she was eligible for citizenship elsewhere.
Her mother is believed to be a Bangladeshi national which means under Bangladesh law Ms Begum would be too.
Ms Begum was a schoolgirl when she left Bethnal Green in 2015. She was found in a Syrian refugee camp last week after reportedly leaving Baghuz – IS’s last stronghold.
She gave birth to a son at the weekend and now wants to return home.
A Home Office spokesperson said decisions to remove citizenship were “based on all available evidence and not taken lightly”.
“In recent days the home secretary has clearly stated that his priority is the safety and security of Britain and the people who live here.”
