points out a Times Online story that says:
"Everyone [in the UK] who buys a mobile telephone will be forced to register their identity on a national database under government plans to extend massively the powers of state surveillance. Phone buyers would have to present a passport or other official form of identification at the point of purchase. Privacy campaigners fear it marks the latest government move to create a surveillance society. A compulsory national register for the owners of all 72m mobile phones in Britain would be part of a much bigger database to combat terrorism and crime. Whitehall officials have raised the idea of a register containing the names and addresses of everyone who buys a phone in recent talks with Vodafone and other telephone companies, insiders say."
