According to Liberty, this raises serious doubts about oversight of the UK Intelligence and Security Commitee and their reassurances that in every case where GCHQ sought information from the US, a warrant for interception signed by a minister was in place.
Eric King, Deputy Director of Privacy international, said:
“We now know that data from any call, internet search, or website you visited over the past two years could be stored in GCHQ's database and analysed at will, all without a warrant to collect it in the first place. It is outrageous that the Government thinks mass surveillance, justified by secret “arrangements” that allow for vast and unrestrained receipt and analysis of foreign intelligence material is lawful. This is completely unacceptable, and makes clear how little transparency and accountability exists within the British intelligence community.”"
