Claim: The 3rd, 4th and 5th boundary reviews for Suffolk, part of its history of Parliamentary constituencies and boundaries, occurred in 1983, 1997 and 2010, respectively; the county has returned 7 MPs to the UK Parliament since 1997.
Evidence: The Third Review, which reflected the changes to local authorities arising from the Local Government Act 1972, did not come into effect until the 1983 general election, when Suffolk's representation was increased back up to 6 MPs. This resulted in major changes to the configuration of the county's seats as follows: The Fourth Review resulted in further major changes with the addition of a seventh constituency, named West Suffolk. This was formed from the majority of the existing Bury St Edmunds constituency, including Newmarket and Mildenhall. It also included Haverhill and surrounding areas, transferred from South Suffolk.
Bury St Edmunds was reconfigured, taking western parts of Central Suffolk, including Stowmarket. Central Suffolk (renamed Central Suffolk and North Ipswich), in turn, gained westernmost parts of Suffolk Coastal, which then gained southernmost parts of Waveney, including Halesworth and Southwold. In the Fifth Review the Boundary Commission for England recommended that Suffolk retain its current constituencies, with changes only to reflect revisions to local authority ward boundaries. The largest of these changes resulted in the effective transfer of one Borough of Ipswich ward from Central Suffolk and North Ipswich to the constituency of Ipswich. The ceremonial county of Suffolk has returned 7 MPs to the UK Parliament since 1997.
