World wide web founder Sir Tim Berners-Lee has said it will be necessary to protest “in the streets” against plans to increase internet monitoring.
Sir Tim told the BBC he was worried there would not be “much control” of the way information was used.
The government has not published its full proposals but says they simply extend existing rules to cover internet phone services and social media.
But Sir Tim said the plans were a “slippery slope”.
The Home Office says the proposals are aimed at tackling crime and terrorism and they are expected to be outlined in full in the Queen’s Speech in May.
