Begum, 21, was one of the three notorious east London schoolgirls who left the UK in February 2015 (when she was only 15) to join the Daesh Takfiri terrorist group in Syria.
Her two companions, Amira Abase and Kadiza Sultana, were subsequently killed in Syria.
Begum was deprived of her British citizenship in February 2019 on the orders of then Home Secretary, Sajid Javid.
She is currently stranded at the Al-Hawl refugee camp in north-east Syria which is run by the Kurdish-dominated Syrian Democratic Forces.
In July the Court of Appeal ruled that Begum can return to the UK to challenge the Home Secretary’s decision to revoke her British citizenship.
That was an important ruling as usually deprivation cases are managed remotely by the Special Immigration Appeals Commission (SIAC), which is often described as the UK’s most secretive court.
The Home Office is challenging the Court of Appeal’s ruling at the Supreme Court, where government barrister, Sir James Eadie QC argued on Monday (November 23) that Begum’s return to the UK “would create significant national security risks”.
The case is seen as a litmus test for many other deprivation cases, where the people involved are invariably stranded abroad and unable to fully participate in SIAC-related legal proceedings.
If Begum wins her case and is allowed to return to the UK to challenge the government’s deprivation decision that may well open the door for other people in similar situations.
Since 2012, 240 people have had their British citizenship revoked by the government on national security grounds.
