Islamic State schoolgirl Shamima Begum's citizenship is to be revoked by the British Home Office, her family's lawyer has said.

Ministers will seek an order "depriving" the 19-year-old Londoner of her British citizenship, solicitor Tasnime Akunjee said.

Ms Begum fled her east London home in 2015 to travel to Syria to support the terror group.

However, she now wishes to return to the UK for the sake of her newly born child as the so-called caliphate crumbles.

In a statement, Mr Akunjee said her "family are very disappointed with the Home Office's intention to have an order made depriving Shamima of her citizenship".

"We are considering all legal avenues to challenge this decision," he added.

Ms Begum was one of three schoolgirls - along with Kadiza Sultana and Amira Abase - from Bethnal Green Academy who left their homes and families to join a fourth Bethnal Green schoolgirl in Syria who had left London the year before.
