In the late 19th century the boundaries of Somerset were slightly altered, but the main change came in 1974 when the county of Avon was set up. The northern part of Somerset was removed from the administrative control of Somerset County Council. On abolition of the county of Avon in 1996, these areas became separate administrative authorities, "North Somerset" and "Bath and North East Somerset". The Department for Communities and Local Government was considering a proposal by Somerset County Council to change Somerset's administrative structure by abolishing the five districts to create a Somerset unitary authority. The changes were planned to be implemented no later than 1 April 2009. However, support for the county council's bid was not guaranteed and opposition among the district council and local population was strong; 82% of people responding to a referendum organised by the five district councils rejected the proposals. It was confirmed in July 2007 that the government had rejected the proposals for unitary authorities in Somerset, and that the present two-tier arrangements of Somerset County Council and the district councils will remain.
