The UK government has drawn up details of its surveillance powers and put them out for a secretive consultation without letting the public know.

The government wants to give itself the ability to monitor British people's communications and force UK firms to include encryption backdoors in their products. Under the proposed Investigatory Powers (Technical Capability) Regulations 2017, telecoms providers must allow the government to simultaneously spy on one in 10,000 of their customers at any time.

Telcos would also have to provide any information the government requests within one working day, and must notify Home Secretary Amber Rudd if there will be any changes to their service, including the development of new services - these will have to be built with the obligations and requirements of the technical capability notice in mind.

Furthermore, telecoms providers must provide backdoors to encrypted data sitting in their services so that the government can access any communications. Telecoms providers must "remove electronic protection applied by or on behalf of the telecommunications operator to the communications or data".

The notice also extends to the postal service, where the government will have the power to "open, copy and reseal any postal item" in order to inspect its contents.
