Shaker Aamer, the last British resident held in Guantanamo prison, is being threatened with transfer to Saudi Arabia.
He fears he will be imprisoned immediately if he is transferred.
Shaker has been held without charge since 2002 and is cleared for release.
He has been on hunger strike for over 150 days in protest at his treatment.
Shaker said, “They will hear me screaming in London if they try to drag me away from here to Saudi Arabia.
“I will resist them every step of the way.”
