The Prime Minister (Mrs Theresa May)

The Department for Energy and Climate Change and the remaining functions of the Department for Business, Innovation and Skills have been merged to form a new Department for Business, Energy and Industrial Strategy, bringing together responsibility for business, industrial strategy, and science and innovation with energy and climate change policy. The new Department will be responsible for helping to ensure that the economy grows strongly in all parts of the country, based on a robust industrial strategy. It will ensure that the UK has energy supplies that are reliable, affordable and clean; and it will make the most of the economic opportunities of new technologies, and support the UK’s global competitiveness more effectively.
