Kate Allen, the director of Amnesty International UK, supports We Stand With Shaker, and says, “We have one simple question for David Cameron: why is Shaker Aamer still in Guantánamo?

“We keep being told that Shaker’s case is being ‘raised’ or being ‘prioritised’, but he’s still sitting in a cell in Cuba, 5,000 miles away from his family back here in Britain.

“Guantánamo has always been a travesty of justice, a lawless place with made-up rules and an Alice in Wonderland approach to justice and human rights.

“We want UK officials to tell us frankly what is causing the disgraceful and inexcusable delay in sorting out Shaker’s case. They must stop toying with this man’s life, and either give him a fair trial or release him and put him on the first plane back to London.”
