Rishi Sunak (Conservative)
On 7 February, I announced the creation of four new Government Departments: the Department for Energy Security and Net Zero; the Department for Science, Innovation and Technology; the Department for Business and Trade; and the Department for Culture, Media and Sport. Following the implementation of those changes, I am announcing the following changes to the sponsorship of public bodies and regulators by these new Departments.
The United Kingdom Atomic Energy Authority will be sponsored by the Department for Energy Security and Net Zero, under the Secretary of State for Energy Security and Net Zero. This will support the Secretary of State in his role to position the UK as a leader in sustainable nuclear energy.
