Campaigners fighting for the release of Guantanamo Bay detainee Omar Deghayes are asking their supporters to send Christmas cards to Tony Blair.

Members of the Save Omar campaign are inviting people to send cards to the Prime Minister, Foreign Secretary Margaret Beckett and Home Secretary John Reid, each complete with an anti-Guantanamo message.

Mr Deghayes, who spent 15 years living with his family in Brighton before he was arrested in Pakistan, has spent more than four years jailed without charge at Camp Delta.

Mr Blair can be reached at 10 Downing Street, London, SW1A 2AA; Mrs Beckett at the Foreign and Commonwealth Office, 19 King Charles Street, London, SW1A 2AH, and Mr Reid at 2 Marsham Street, London, SW1P 4DF.
