Cori Crider of the campaign group Reprieve has called on the Foreign Secretary William Hague to do more to ensure the release of Shaker Aamer, the Londoner who is still being held in Guantanamo Bay.
The director of the legal charity Reprieve has urged the UK Government to do more to help Shaker Aamer.
A South Londoner who is being held in the US detention camp in Guantanamo Bay has gone on hunger strike. Shaker Aamer has been held at the base for eleven years but has not been tried or charged.
Mr Aamer has said he has lost over 30 pounds since he joined the strike. Lawyers for the inmates say around three-quarters of them have gone on hunger strike at the camp.
