A group of students at a school in London have started a petition demanding that the city council stop the deportation of an Iraqi refugee and her daughter. The petition, signed by more than 11,000 people, is aimed at London Mayor Sadiq Khan, who has the power to stop the deportation of Iraqis in the country who are not British nationals. It comes after the Home Office announced last week that it was looking at deporting Aqsa Mahmood, 24, and her daughter, who is in year 12, to Iraq. Aqsa, who fled the Islamic State group with her family in 2014, said she was “in fear” of her life if she was sent back to Iraq. Ms Mahmood has lived in the UK since she was six and has a British husband, but is not a British citizen. She and her husband have four-year-old twin sons and her husband has been granted a spousal visa to remain in the country. The petition on the website of the London Student Human Rights Campaign says: “Iraqi citizens who are in the UK, but are not British citizens, must not be deported.
