Proposals for a new unitary authority covering Buckinghamshire have been given the backing of the government.
The plans would be the county council and four district councils – Aylesbury Vale, Chiltern, Wycombe, and South Bucks – replaced with one authority.
The scheme for one local authority has been proposed by the county council.
The government said it was "minded" to a single authority.
Communities Secretary Sajid Javid said: "There is broad local consent for change in Buckinghamshire.
Buckinghamshire with a single council for the area. "Having carefully considered all the material and representations I have received, I am at least to implement, subject to parliamentary approval and further discussions.
"I am satisfied that this new single council, if established, is likely to improve local government and service delivery in the county, generating savings, increasing financial resilience, facilitating a more strategic and holistic approach to planning and housing challenge."
County Council Leader Martin Tett said: "We know there is widespread support for these proposals and we want to continue talking with people and developing a wide range of organizations across the county to ensure that they deliver their input and expertise as things develop."
In a joint statement, the four district councils said, "While we are extremely disappointed, the 'minded to' decision is not set in stone and as the process allows, we want to make the strongest possible representation to the Secretary of State that this decision is not the right one.
"We do not believe this decision is in the best interest of our local residents, businesses, community groups, parish councils and various other stakeholders across the county and, based on our own commitment, we do not believe it has strong local support. "
