It is in a ruling in the so-called Court of Appeal, the instance under the Supreme Court, that Begum's right to have his case tried is established, reports the BBC. "Justice in this case must outweigh national security," the court said, stating that Begum was never given an opportunity for a fair trial of her case because she could not leave Syria.

"A disappointment"

The ruling is criticized by the British Home Office. "This decision is a disappointment. [...] The government's highest priority is to maintain our national security and protect the population ", it says in a statement.

Under international law, citizenship can only be revoked if the person in question is also a citizen of another country. Shamima Begum certainly has her roots in Bandgladesh, where, according to British authorities, she could apply for citizenship. But the country's government does not want to receive her.

Posed a security risk

Begum traveled to Syria five years ago with two other young girls from London. Her citizenship was revoked four years later when she was found in a Syrian camp. According to the British Government, she posed a security risk.

In a high-profile interview with the TV channel Sky, Begum considered that "many people should have sympathy for me given everything I have been through".
