Cheshire West and Chester is a non-metropolitan county, non-metropolitan district and unitary authority with borough status in the ceremonial county of Cheshire. It was established on 1 April 2009 as part of the 2009 structural changes to local government in England, by virtue of an order under the Local Government and Public Involvement in Health Act 2007. It superseded the boroughs of Ellesmere Port and Neston and Vale Royal and the City of Chester and its council assumed the functions and responsibilities of the former Cheshire County Council within its area. The remainder of ceremonial Cheshire is composed of Cheshire East, Warrington and Halton.
