Breaking news. This is the BBC. Getting court declarations reported accurately is still something I can rely on from the BBC.
Shamima Begum, who left the UK to join the Islamic State group as a teenager, will not be allowed to return and fight her citizenship case, the Supreme Court has ruled.
In an unanimous ruling, the court said the government did not breach her rights by refusing to allow her back.
Ms Begum, 21, wants to return to challenge the home secretary's decision to remove her British nationality.
Possibly more to follow shortly. This is just her presence in the country to argue her case that has been refused; not the appeal to have citizenship restored, or its revokation revoked. That application is still to be heard but will be argued by her lawyers in her absence, with instructions taken from either her parents or her at distance.
