More than 2,300 people from all parts of Wales have also signed the petition, which asks that former law student Omar Deghayes should be returned to the United Kingdom after more than five years in custody without charge or trial.

It also seeks assurances that he will not be sent to a country where he will face further torture. One Libyan security agent who interviewed him in Guantanamo reportedly threatened: "In here I cannot do anything, but if I meet you later I will kill you if you don't kill me."

Welsh Members of Parliament and Assembly Members from all parties have endorsed the appeal, which was presented at 10 Downing Street, home of the British Prime Minister, on Wednesday, July 18, by four members of the campaign's steering group, who were joined by Deghayes' mother and brother.

The Anglican Archbishop of Wales, the Most Rev. Dr. Barry Morgan; the Catholic Archbishop of Cardiff, the Most Rev. Peter Smith; and the President of the Free Church Council for Wales, the Rev. Pamela Cram, added their signatures during a brief ceremony at Ararat Baptist Church, Whitchurch, Cardiff at 2 p.m. on Monday, July 16.

Deghayes, 36, whose father was executed by the Libyan secret police in 1980, has had refugee status in the U.K. since 1986, when his mother fled Libya with her five children. He was arrested in Pakistan with his Afghani wife and their young son (both later released). He was subsequently detained at Bagram, before being transferred to Guantanamo Bay more than four years ago. He says he has been tortured in three countries.

The petition has been raised by the Welsh churches human rights campaign, Christians Against Torture, which insists that torture is always unacceptable in all circumstances. The campaign's supporters have sent Deghayes hundreds of greetings over the past 18 months, and made many appeals on his behalf.
