Plans are being made to scrap Bedfordshire County Council, according to Bedford MP Patrick Hall.
He says all services in Bedfordshire will be controlled by Bedford Borough Council and a merger of South Beds and Mid Beds district councils.
Luton is already a unitary authority. The official decision on unitary status is expected to be announced by the government in the afternoon.
The announcement is part of a series of changes to local government.
Any approved new unitary councils are expected to come into place in April 2009.
