Protestors calling for Guantanamo Bay detainee Omar Deghayes to be brought back to Britain say their campaign is going from strength to strength.

Mr Deghayes, a 35-year-old father from Saltdean, has been held by the US military since 2002 but has never been charged with any crime.

Campaigners have marched through Brighton, lobbied parliamentary candidates and sat in tiny cells outside public buildings to draw attention to Mr Deghayes' detention.

Lawyer Clive Stafford Smith has visited Mr Deghayes and said he has suffered alleged abuse at the hands of his American captors.

The prisoner complained of having a hose stuck up his nose until he was drowning, electric shock torture and being placed in a room painted with black and white stripes, containing a glass wall, behind which were snakes.

Mr Stafford Smith added his client had been told his wife would be sold into prostitution when he was first taken into custody.

The allegations have fuelled sympathy for Mr Deghayes' plight and protesters say more people are joining the campaign and writing to Tony Blair demanding the US Government is persuaded to send Mr Deghayes home.

Teachers at some schools have started discussing Mr Deghayes' plight in citizenship classes, after the National Union of Teachers for West Sussex gave its support to the campaign.

Campaigners now hope to make the same thing happen at schools in Brighton and Hove.

On Friday, about 100 people attended a concert for Mr Deghayes at the Friends Meeting House in Ship Street, Brighton.

Jackie Chase, of the Save Omar campaign, said: "During his last visit with Clive Stafford Smith, Omar said he was really moved by how much support there has been for him in Brighton.

"The message has got through to him that people really care and are determined to get him brought home."

She said the campaign was getting a better response from ministers at the Foreign and Commonwealth Office. She said: "When I am handing out leaflets there is a much greater level of awareness of who Omar is."
