Global InformationHistory of parliamentary constituencies and boundaries in Oxfordshire information
The ceremonial county of Oxfordshire has returned six MPs to the UK Parliament since 1983.
As a result of the local government reorganisation introduced by the Local Government Act 1972, which came into effect on 1 April 1974, the boundaries of the historic/administrative county were altered to include northern parts of the county of Berkshire. This was reflected in the following redistribution of parliamentary seats which came into effect for the 1983 general election and effectively increased the county's representation from four to six MPs.
