Campaigners have reacted with "dismay" to a report by MPs defending the Government's refusal to stand up for British residents at Guantanamo Bay.

The House of Commons Foreign Affairs Committee, in a report published on Sunday, said: "The Government is right to stick to its established policy of not accepting consular responsibility for non-British nationals."

The committee's decision to back the Government's inaction came despite its assessment that "abuse of detainees in Guantanamo Bay has almost certainly taken place".

Omar Deghayes, who lived in Brighton for 15 years before he was arrested in Pakistan, has been held in Camp Delta for more than five years without charge.

Louise Purbrick, of the Save Omar campaign, said: "I can see a British embassy may not feel obliged to help someone who was not a full British national if, say, they lost their handbag on holiday.

"But you would think that being tortured in jail, which every reputable international body has condemned, might warrant greater compassion."
