Last Briton in Gitmo being held to 'silence' torture claims, UK MPs hear

Lawmakers Urge Release of UK Guantanamo Detainee | Al Jazeera America: 
Aamer, a Saudi national and resident of the U.K., has been held at the U.S. detention facility without charge or trial since February 2002, despite being cleared for release twice, once by the Bush administration in 2007 and subsequently by the Obama administration in 2009.
“Shaker’s release has become urgent,” said Labour Party MP John McDonnell during the parliamentary debate about his continued imprisonment. “We want Shaker released and returned to his family.”
During the debate, MPs raised what was described as "deeply damaging" allegations regarding the real reason some believe Aamer has not been released: that he was present during human rights abuses conducted by authorities.
