Global spy system ECHELON confirmed at last – by leaked Snowden files

Origins of automated surveillance

Special Report Duncan Campbell has spent decades unmasking Britain's super-secretive GCHQ, its spying programmes, and its cosy relationship with America's NSA. Today, he retells his life's work exposing the government's over-reaching surveillance, and reveals documents from the leaked Snowden files confirming the history of the fearsome ECHELON intercept project. This story is also published simultaneously today by The Intercept, and later today we'll have video of Duncan describing ECHELON and related surveillance matters."
