Powers conferred by government regulations during a state of emergency. The existence of such a state is declared by royal proclamation under the Emergency Powers Acts 1920 and 1964 and the Civil Contingencies Act 2004. A proclamation, which lasts for one month but is renewable, may be issued whenever there is a threat (e.g. a major strike or natural disaster) to the country's essentials of life. The regulations made may confer on government departments, the armed forces, and others all powers necessary to secure the supply and distribution of necessities and the maintenance of public peace and safety.
