The Draft Communications Data Bill (nicknamed the Snoopers' Charter or Snooper's Charter) is draft legislation proposed by then Home Secretary Theresa May in the United Kingdom which would require Internet service providers and mobile phone companies to maintain records of each user's internet browsing activity (including social media), email correspondence, voice calls, internet gaming, and mobile phone messaging services and store the records for 12 months. Retention of email and telephone contact data for this time is already required by the Data Retention Regulations 2014. The anticipated cost is £1.8 billion.
