The debate came after Lord Reed, the president of the Supreme Court, said the government could prevent Ms Begum from returning to the UK, on Friday.
He said: “The Supreme Court unanimously allows all of the home secretary’s appeals and dismisses Ms Begum’s cross-appeal.”
Lord Reed also added the Court of Appeal “has mistakenly believed that, when an individual’s right to have a fair hearing… came into conflict with the requirements of national security, her right to a fair hearing must prevail”.
