"The Americans were very keen that people like us did not discover what they were doing," Manningham-Buller told a meeting at Britain's Parliament.
Britain's spy agencies have come under heavy criticism for their alleged collusion in the torture overseas of terrorist suspects, including detainees held in U.S. custody.
In a recent court ruling, one of Britain's most senior judges questioned MI5's record on human rights and claimed the agency may have misled Parliament and the courts about how much it knew about mistreatment. Manningham-Buller said that in 2002 or 2003 she questioned how the U.S. was able to supply Britain with intelligence gleaned from Sheikh Mohammed.
