In a potential area of controversy, measures requiring internet firms to store internet connection records (ICR) to respond to the increasing use of apps and social media for communication are expected to be included in the draft Investigatory Powers Bill.

Security services will retain the capacity to intercept the content of communications after obtaining a warrant.

The Prime Minister's official spokeswoman said Home Secretary Theresa May talked colleagues through the powers contained in the legislation.
The independent reviewer of terrorism legislation, David Anderson QC, gave a comprehensive 370-page report in June that heavily influenced Government thinking and the Investigatory Powers Bill.
