A giant database of every phone call and email sent in Britain is being considered by the Government.
Internet service providers and telephone companies would be forced to hand over records to the Home Office, which would keep them on a computer system.
All forms of electronic communication face being monitored, including social networking sites and text messages.
The database would also include details of how long individuals spend on the internet.
The government would retain the data for 12 months and security services and police could seek court permission to access it in the fight against terrorism.
Last night, however, opponents reacted with horror, branding them disproportionate and an 'Orwellian step too far', not least because the Government has an appalling record at keeping data.
Britain is already one of the most watched nations on the planet.
