The campaign to bring Guantanamo Bay detainee Omar Deghayes home is gaining ground as fears grow he could be sent to Libya if the camp closes.

US President George Bush raised speculation the prison camp could close in a TV interview when he failed to rule out the possibility.

He said: "We're exploring all alternatives as to how best to do the main objective, which is to protect America."

American public opinion is turning against the Cuban prison camp following accusations detainees are being mistreated there. There are also concerns about the damage the camp is doing to America's image overseas.

Family members and supporters fear Mr Deghayes, 35, from Saltdean, could be sent to Libya if the camp closes as he is a British resident, not a citizen.

His father was allegedly assassinated by the Libyan government and Libyan interrogators are said to have threatened him at Guantanamo, where he has been detained without charge since 2002.

Jackie Chase, of the Brighton-based Save Omar campaign, said: "The noises coming from America are that they are going to release him to go to Libya, which amounts to murder when you think about it."

A meeting discussing Mr Deghayes' plight will be held today at human rights lawyer Clive Stafford Smith's offices in Canary Wharf, London.

Libyan politics expert George Joffe, of Kings College London, will be there along with Mr Deghayes' brothers Taher and Abu Baker.

His sister Amani Deghayes said the campaign was still going strong and she had spoken about him at anti-war meetings in Huddersfield, London and Leeds. She said: "It is so encouraging that people are still supporting him and trying to help him but at the moment we are at a political stalemate.

"I am just hoping people will keep lobbying their MPs. George Galloway has agreed to raise Omar's case in the House of Commons and that's a positive step."
