Screenshot of the first 4 paragraphs of the linked BBC News article: The home secretary will "robustly defend" the decision to strip Shamima Begum of her British citizenship, as European judges scrutinise the move, according to a government source. The European Court of Human Rights (ECHR) has called for an investigation, but a government source said the decision had already been upheld by UK courts. Ms Begum was 15 when she travelled from east London to the Middle East, to a territory held by the Islamic State group, where she married a fighter. Now 26, she was subsequently stripped of her British citizenship on the grounds that she posed a threat to national security but her lawyers say this failed to consider whether she was a victim of grooming and trafficking.
