The new data laws being rushed through parliament are to ensure "vital" criminal evidence against criminals can be collected, Downing Street said.
Every major counter-terrorism investigation and 95% of CPS cases against organised crime over the past decade have used evidence from phones and computers, Number 10 said, including:
- The murder of 11-year-old Rhys Jones, shot in the back in Liverpool in 2007. Mobile phone information showed the killers were in contact, and in key locations
- The gang of men who groomed girls in Rochdale were prosecuted after phone data showed they were in contact with each other and their victims
- A Europol investigation into sexual exploitation of children online identified 371 suspects in the UK, with 240 cases investigated and 121 arrests or convictions - in contrast to Germany where data is not kept, which identified 337 suspects, but investigated only seven and made no arrests
