Expert lawyers with experience in Bangladeshi citizenship cases have told the BBC that under Bangladesh law, a UK national like Ms Begum, if born to a Bangladeshi parent, is automatically a Bangladeshi citizen.That means that such a person would have dual nationality.
If the person remains in the UK, their Bangladeshi citizenship remains in existence but dormant.
Her Bangladeshi citizenship, if established, would remain intact until she reaches 21, even if she has never visited the country or made active efforts to retain her citizenship.
As a British citizen, Ms Begum's child would have a right to enter the UK. However the British government has no consular staff in Syria to help get him out of the country.
The home secretary has the power to strip an individual of their British citizenship on the basis that it is "conducive to the public good", as long as the person would not become stateless as a result.
