Begg's American lawyer, Gitanjali Gutierrez of the Center for Constitutional Rights, received a handwritten letter from him, dated 12 July 2004, addressed to the US Forces Administration at Guantanamo Bay. It was copied to Begg's lawyers, and the US authorities agreed to declassify it. Its full text was passed to his British lawyer, Gareth Peirce. He insisted: "I am a law-abiding citizen of the UK, and attest vehemently to my innocence, before God and the law, of any crime — though none has even been alleged".
