THE international director of advocacy group Cage pledged to fight his conviction under anti-terror legislation at the Supreme Court yesterday after the High Court rejected his appeal.

Muhammad Rabbani refused to provide the passwords to his electronic devices at Heathrow airport in November 2016 in order to protect documents detailing the torture of Qatari businessman Ali al-Marri by FBI agents.

Some of the files were among a cache of 35,000 documents published by Cage last month, which named six agents involved in Mr Marri’s torture on US soil.
