The government will be able to monitor the calls, emails, texts and website visits of everyone in the UK under new legislation set to be announced soon. Internet firms will be required to give intelligence agency GCHQ access to communications on demand, in real time. The Home Office says the move is key to tackling crime and terrorism, but civil liberties groups have criticised it. Tory MP David Davis called it an unnecessary extension of the ability of the state to snoop on ordinary people". A new law ... would not allow GCHQ to access the content of emails, calls or messages without a warrant. But it would enable intelligence officers to identify who an individual or group is in contact with, how often and for how long. They would also be able to see which websites someone had visited. Conservative MP and former shadow home secretary David Davis said it would make it easier for the government "to eavesdrop on vast numbers of people". "What this is talking about doing is not focusing on terrorists or criminals, it's absolutely everybody's emails, phone calls, web access..." He said that until now anyone wishing to monitor communications had been required to gain permission from a magistrate. Nick Pickles, director of the Big Brother Watch campaign group, called the move "an unprecedented step that will see Britain adopt the same kind of surveillance seen in China and Iran". The previous Labour government attempted to introduce a central, government-run database of everyone's phone calls and emails, but eventually dropped the bid after widespread anger.
