# Third periodic review of Westminster constituencies

The third periodic review of Westminster constituencies was undertaken in the United Kingdom between 1976 and 1983 by the four boundary commissions. The reviews took account of the major local government reorganisations that had become effective in 1974, and resulted in significant changes to the electoral map. The previous 635 seats were replaced with 650 constituencies, of which 90% were newly created or significantly revised. The new boundaries were first used for the 1983 general election.

## Review process

Under the terms of the House of Commons (Redistribution of Seats) Act 1958, the boundary commissions were required to present their final recommendations between 10 and 15 years after the submission of their previous reports. As the final reports for the second periodic review had been submitted between April and June 1969, the final reports for the Third Review were due to be submitted no later than June 1984. Accordingly, the English Commission had commenced their review in March 1976, anticipating that its review would take three years and would be complicated by the level of change to the local government boundaries. In the event, the review took over six years, mainly as a result of delays to the work of the Local Government Boundary Commission for England. The Scottish and Welsh commissions commenced their reviews in February 1978 and February 1981 respectively, again experiencing problems with delays to local government boundary reviews. The process in Northern Ireland was delayed pending consideration of the province's representation by a Speaker's Conference. This resulted in an increase from 12 to 17 seats, as enacted by the House of Commons (Redistribution of Seats) Act 1979.
The final reports were submitted as follows:
* Northern Ireland - 27 October 1982
* Wales - 21 January 1983
* England - 1 February 1983
* Scotland - 18 February 1983

## Changes
### England

As a result of the creation of six metropolitan counties and three new non-metropolitan counties (Avon, Cleveland and Humberside - all now abolished), many existing constituencies now crossed county boundaries, with some lying in three or even four counties (e.g. Goole, formerly in the West Riding of Yorkshire, included parts in Humberside, North Yorkshire, South Yorkshire and West Yorkshire; and Newton, formerly in Lancashire, straddled Greater Manchester, Merseyside and a reconfigured Cheshire). Given the ancient tradition that constituency boundaries ought not to cross county boundaries, the configuration of the constituencies was, consequently, radically changed – particularly in the North of England. Although there was a redistribution of the number of seats in London, the South and the Midlands, the overall disruption to the existing layout was more limited as these areas were less affected by the local government reorganisation.
The Review abolished many long-established constituencies, such as Abingdon, Bedford$^1$, Clitheroe, Colchester$^1$, Eye, Hastings, Kidderminster, Morpeth, Oxford, Paisley, Petersfield, Ripon, Rye, Totnes$^1$ and Warrington, which had all been in existence since at least 1832.
$^1$ These were re-established at subsequent reviews.
The summary of changes below highlights newly created constituencies in bold and abolished ones in italic. Continuing seats are in plain text.
Overall, the English Commission increased the number of seats by seven, from 516 to 523.

Blaby, Harborough, Leicester East, Leicester South and Leicester West were unchanged.

##### Lincolnshire (6)

Changes to the county boundary and the absorption of the county of Rutland by Leicestershire lead to significant changes.

Grantham and Holland with Boston both lost parts of their electorates, whilst Lincoln was expanded.

##### Northamptonshire (6)

Corby created from substantial areas of Kettering and Wellingborough. Parts of the new town of Northampton in Daventry transferred to both Northampton North and Northampton South.

In the city of Nottingham, significant changes were made to Nottingham East and Nottingham North, with Nottingham South replacing Nottingham West.

Three new seats of Central Suffolk, South Suffolk and Suffolk Coastal were created as a result of the abolition of Eye and Sudbury and Woodbridge and substantial reductions in the electorates of Bury St Edmunds and Ipswich. Lowestoft was renamed Waveney with only minor changes.

The existing Cardiff North seat was subsumed into the new seat of Cardiff Central, with a virtually unchanged Cardiff North West then renamed Cardiff North. Cardiff Central also included part of Cardiff South East, the remainder of which formed the majority of Cardiff South and Penarth - the town of Penarth having been previously part of Barry. The remainder of Barry formed the majority of Vale of Glamorgan, which included a part of Pontypridd (see Mid Glamorgan). There was a minor change to Cardiff West.

#### West Glamorgan (5 seats)

Part of Aberavon was included in the new seat of Bridgend (see Mid Glamorgan) which resulted in knock-on changes to Neath, Gower, Swansea East and Swansea West.
