British police are to be given the power to view the entire Internet history of everyone in the U.K. in a new surveillance bill to be published next week, reports say.

Under the proposed plan, telecoms and Internet service providers will be legally required to retain all Web browsing history for all customers for a period of 12 months, according to The Daily Telegraph.

The Guardian reports that “senior officers want to revive the measures similar to those contained in the ‘snooper’s charter,’ which would force telecommunications companies to retain for 12 months data that would disclose websites visited by customers.”

It comes as David Cameron, the Prime Minister, announced moves to strengthen its treaty with America to ensure Internet companies based there hand over requested data on suspects.

Some of the largest companies have been increasingly reluctant to supply customer communications in the wake of the claims of mass surveillance programmes by former CIA contractor Edward Snowden.
