Communications Capabilities Development Programme

The Communications Capabilities Development Programme (CCDP) is a UK government initiative to extend the government's capabilities for lawful interception and storage of communications data. It would involve the logging of every telephone call, email and text message between every inhabitant of the UK, (but would not record the actual content of these emails) and is intended to extend beyond the realms of conventional telecommunications media to log communications within social networking platforms such as Twitter and Facebook.
