Shamima Begum joined the Islamic State (IS) group when she was 15 years old. In 2019, his citizenship was stripped of his citizenship by the British Home Office for reasons of national security.

The court of appeal had to rule on the illegality of this decision. She lives in a camp in Syria so cannot return to the UK. She says she is the victim of trafficking set up by ISIS in order to marry her. The director of the British human rights NGO Reprieve, Maya Foa, believes that deprivation of nationality is not a satisfactory answer.
