Shamima Begum has lost a legal challenge over the decision to deprive her of her British citizenship.
Ms Begum was 15 years old when she travelled from Bethnal Green, east London, through Turkey and into territory controlled by the so-called Islamic State (IS).
Her British citizenship was revoked shortly after she was found, nine months pregnant, in a Syrian refugee camp in February 2019.

Ms Begum, now 23, brought a challenge against the Home Office over this decision at the Special Immigration Appeals Commission (SIAC), a specialist tribunal which hears challenges to decisions to remove someone’s British citizenship on national security grounds.
Following a five-day hearing in November, the tribunal dismissed her challenge on Wednesday. The judgment means she will not able to win back her British passport.
At the hearing last year, Ms Begum's barristers Samantha Knights KC and Dan Squires KC said she was “recruited, transported, transferred, harboured and received in Syria for the purposes of ‘sexual exploitation’ and ‘marriage’ to an adult male”.
They also argued that the Home Office unlawfully failed to consider that she travelled to Syria and remained there “as a victim of child trafficking”.
However, Sir James Eadie KC, for the department, said the security services “continue to assess that Ms Begum poses a risk to national security”.
Sir James later said then-home secretary Sajid Javid took into account Ms Begum age, how she travelled to Syria – including likely online radicalisation – and her activity in the country, when deciding to remove her British citizenship.
Giving the decision of the tribunal, Mr Justice Jay said that “reasonable people will differ” over the circumstances of Ms Begum's case.
He said: “The commission has fully recognised the considerable force in the submissions advanced on behalf of Ms Begum that the Secretary of State’s conclusion, on expert advice, that Ms Begum travelled voluntarily to Syria is as stark as it is unsympathetic.
“Further, there is some merit in the argument that those advising the Secretary of State see this as a black and white issue, when many would say that there are shades of grey.”
He continued: “If asked to evaluate all the circumstances of Ms Begum's case, reasonable people with knowledge of all the relevant evidence will differ, in particular in relation to the issue of the extent to which her travel to Syria was voluntary and the weight to be given to that factor in the context of all others.
“Likewise, reasonable people will differ as to the threat she posed in February 2019 to the national security of the United Kingdom, and as to how that threat should be balanced against all countervailing considerations.
“However, under our constitutional settlement these sensitive issues are for the Secretary of State to evaluate and not for the commission.”
The Home Office has said it is “pleased” with the court's ruling.
In a statement, a spokeswoman said: “We are pleased that the court has found in favour of the Government’s position in this case.
“The Government’s priority remains maintaining the safety and security of the UK and we will robustly defend any decision made in doing so.”
Steve Valdez-Symonds, Amnesty International UK’s refugee and migrant rights director, described the Shamima Begum ruling as a “very disappointing decision”.
