12. UK spy chiefs emerge from shadows to blast Edward Snowden
Iain Lobban, the director of GCHQ, Britain's electronic eavesdropping agency, told lawmakers that intelligence chiefs were "actively considering" whether more information should now be shared with the public as a result.
Visibly emotional, he argued however that "certain methods" should remain secret and cited what he said were specific examples where the Snowden data leaks had harmed Britain's national security.
"We've seen terrorist groups in the Middle East, in Afghanistan and elsewhere in south Asia discussing the revelations in specific terms," he said.
"We have actually seen chat around specific terrorist groups who, even close to home, discuss how to avoid what they now perceive to be vulnerable communications methods, or how to select communications which they now perceive not to be exploitable."
