Overview
Dorset is a unitary authority area, existing since 1 April 2019, in the ceremonial county of Dorset, England. It covers all of the ceremonial county except for Bournemouth, Christchurch and Poole. The council of the district is Dorset Council, which is in effect Dorset County Council re-constituted so as to be vested with the powers and duties of five district councils which were abolished, and shedding its partial responsibility for and powers in Christchurch.
History and statutory process
Statutory instruments for re-organisation of Dorset (as to local government) were made in May 2018. These implemented the Future Dorset plan to see all councils then existing within the county abolished and replaced by two new unitary authorities on 1 April 2019.
The unitary authorities of Bournemouth and Poole merged with the non-metropolitan district of Christchurch to create a single unitary authority called Bournemouth, Christchurch and Poole Council, which has since created a BCP abbreviation in much of its work and amenities, to serve the coastal conurbation.
Weymouth and Portland, West Dorset, North Dorset, Purbeck and East Dorset (non-metropolitan districts) combined with the functions vested in Dorset County Council to form Dorset Council.
Rationale and other tiers of government
As regards to planning decisions, highways, cleaning, education and social care no confusion remains as to the potentially relevant body (including occasional open conflict of powers/responsibilities) between two tiers of local government (which can be the case where county and district councils co-exist).
