Companies will have to tell police who was using a PC or a mobile phone and as part of the proposed bill, ISPs will have to keep IP data that links users to their devices.
The additional powers were originally part of the so-called “snoopers’ charter” which was abandoned after widespread protests.
May claims that the proposal will help it fight terror suspects, paedophiles, hackers, and crooks. She made the case over the weekend that police should be able to access far more communication data in the snopers’ charter, which was rejected by the Tory Party’s coalition partner, the Liberal Democrats.
However, the head of the Liberal Democrats, Nick Clegg, said the latest moves were acceptable and reasonable.
