The majority of Britons are concerned about their online privacy and back an investigation into internet giant Google's data policies, campaigners have said.
A survey by privacy campaign group Big Brother Watch found that 68% of respondents are concerned about online privacy with nearly a quarter "very concerned".
Google was ultimately given four months to change its approach with 12 "practical recommendations" published by the group of regulators.
However, last week the French authority leading the investigation - CNIL - said "Google did not provide any precise and effective answers" and regulators will now meet on February 26 to discuss how to proceed.
Mr Pickles added: "People increasingly feel their interests and privacy are being ignored by large companies and advertisers motivated by profit. If regulators don't get a grip of the situation we risk people losing trust in the digital economy and feeling they are not in control of their personal information. The long term consequences of such a collapse in trust would be dire."
The survey, undertaken by ComRes, interviewed 2,050 British adults online between February 15 and February 17.
