MPs, celebrities and of course the family of Shaker Aamer are pleading for his release from Guantanamo, following the recent Senate report into CIA torture of terror suspects.

The Battersea father, who now suffers from post traumatic stress disorder, has spent 13 years in the notorious Cuban prison without charge.

The We Stand With Shaker campaign is begging David Cameron to persuade Barack Obama to release Mr Aamer, 46.

There has been global outrage at the US Senate report into torture by the CIA. Mr Aamer said he had been beaten and starved, and his lawyers say he is still being held because they fear he will blow the whistle on further torture by the West.

He claims he was present when another detainee, Ibn Sheikh al-Libi, was abused in front of British intelligence officers. Part of al-Libi’s evidence was used to justify the invasion of Iraq in 2003.

His MP, Jane Ellison, has continued her campaign to get Mr Aamer back home. She said: “Shaker Aamer’s continued detention in Guantanamo Bay is unacceptable.

“The UK Government has confirmed repeatedly that they want him released to the UK and the latest revelations serve to underline that Shaker Aamer should be immediately reunited with his family in Battersea. I am delighted that the Foreign Office continues to push for his release.

“This is a very urgent matter, and, amidst the current controversy about Guantanamo, I want to ensure that the dreadful situation facing my constituent right now is not forgotten. His release is long, long overdue and I hope his family in my constituency will not have to wait any longer to hear good news.”

Ms Ellison has written to the US Special Envoys for the Closure of Guantanamo, Clifford Sloan and Paul Lewis, asking that Mr Aamer is released immediately.

Mr Aamer, who has a wife and four children in Wandsworth, is accused of being a close associate of Osama bin Laden, which he denies.

He has been cleared for transfer by both the Bush and Obama administrations, according to Reprieve, the legal charity and human rights group which is representing him.

Last year Prime Minister David Cameron raised Mr Aamer’s case with President Barack Obama at a G8 summit and the British government has repeatedly stated that it wants him returned to the UK.
