More international figures have backed a campaign by The Argus to secure justice for Guantanamo Bay prisoner Omar Deghayes.

The Archbishop of York and Liberal Democrat acting leader Sir Menzies Campbell have added their names to a list which already includes UN Secretary General Kofi Annan, Archbishop Desmond Tutu and Northern Ireland Secretary Peter Hain.

The pressure on the Government to intervene over the Guantanamo Bay situation follows a report by the United Nations which advised the camp, where US authorities are holding terror suspects, should be closed immediately because prisoners are being tortured.

Last Thursday a senior High Court judge, Mr Justice Collins, spoke out about the situation.

The campaign's gathering momentum has brought about new hope for the family of Brighton law graduate Omar Deghayes, 35, who has been imprisoned at the camp without trial since he was seized in Pakistan in 2002.

He was taken after being recognised as appearing in a terrorist training video but his family says it is a case of mistaken identity.

The Argus, which has been campaigning for Mr Deghayes to be tried or released from the camp since last summer, has sent a 36-page dossier to Tony Blair urging him to petition the US Government.

So far the Government has insisted it cannot intervene in the case of Mr Deghayes because he does not hold a British passport.
