'Traitor’ Snowden endangered spies with NSA leaks, claim UK security chiefs
While being questioned by MPs on Monday, Home Secretary Theresa May said: “I assess and so does the director general of MI5 that the Snowden leaks did cause damage.
“It has had an impact on the ability of our agencies to do the work they need to do. It would be fair to say it has had an impact not just on agencies in the UK.
“If work has been done to try to mitigate the impact, that uses resources.”
Her position reflects that of other senior ministers. Conservative MP Michael Ellis, who serves on the Home Affairs Select Committee, told the Daily Mail: “It is clear to me the damage Snowden has done is monumental.
“Not only has he jeopardized national security by his leaks, but he has also put people at risk and it is clear that he has also caused considerable financial loss.”
While Snowden has said his decision to leak was in response to what he perceived as a “threat to democracy,” the former NSA analyst has consistently been a focal point of British security officials’ ire.
Lord West, who served as both an admiral and a security minister, previously told the paper: “Since the revelations of the traitor Snowden, terrorist groups – in particular ISIL (the so-called Islamic State) – have changed their methods of communications and shifted to other ways of talking to each other.
“Consequently there are people dying who actually would now be alive.”
In 2013, Snowden began a series of leaks of classified information on secret intelligence activities.
His exposure of the extent of mass surveillance helped to inform a landmark investigation into the activities of British surveillance agency GCHQ – the UK equivalent of the NSA.
Last month a UK court ruled that mass surveillance of internet communications by British intelligence agency GCHQ up to the end of 2014 was “unlawful.”
The Investigatory Powers Tribunal (IPT) announced on Friday the security agency’s access to information obtained by the NSA was in breach of human rights law.
