Britain has turned over classified material to U.S. military prosecutors at Guantánamo Bay about a British prisoner’s allegations that he was interrogated and tortured in Morocco after secretly being taken there by the CIA.

The prisoner, Binyam Mohamed, was charged by U.S. military prosecutors last month with conspiracy and material support for terrorism, and the Foreign Office said in a letter to his lawyer that the evidence it gave to the Pentagon could be “exculpatory and relevant.”

In the letter, which has not been made public, the Foreign Office acknowledged that it had previously denied – to the defendant’s lawyers and to a parliamentary committee – having had any information pertaining to Mohamed.

The Foreign Office told the lawyer, Clive Stafford Smith, that it could not reveal the contents of the classified material, but that the U.S. prosecutors had an obligation to turn it over to the defense before any trial.

The Foreign Office wrote June 6 to Stafford Smith. “We have…written to the U.S. authorities asking them to investigate Mr. Mohamed’s allegations of mistreatment.”

The U.S. State Department informed the British Embassy in Washington this year that there would not be an investigation.

Mohamed has said that while in Morocco, the torture included being cut on his chest and genitals with a razor. Stafford Smith has said that photographs were taken of Mohamed’s injuries by U.S. military personnel.

We have one batch of sleazy, lying politicians admitting their complicity with another batch of sleazy, lying politicians. Denying responsibility. Ignoring human rights that help define how we differ from terrorist fanatics.

How can you have anything other than contempt for either gang of self-serving bureaucrats?
