The Greater London Authority, a unique governance structure established in 2000, covers the 32 London boroughs and has significant autonomy in areas like transport, housing, and policing. The South East of England has no devolution deal and its has significant intra-regional divides are compounded the lack of a coordinated regional voice through a Metro Mayor or other institution. Bristol, South Gloucestershire, Bath and North East Somerset established the West of England Combined Authority in 2017, with a focus in planning, skills development, local transport, and business support. In 2015, Cornwall became the first rural unitary authority to successfully negotiate a devolution deal but turned down a mayoral devolution deal in 2023.
