[1] 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.
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.
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 process in Northern Ireland was delayed pending consideration of the province's representation by a Speaker's Conference.
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, Bedford1, Clitheroe, Colchester1, Eye, Hastings, Kidderminster, Morpeth, Oxford, Paisley, Petersfield, Ripon, Rye, Totnes1 and Warrington, which had all been in existence since at least 1832.
North West Leicestershire created, comprising over half of Loughborough and a substantial part of Bosworth.
Sherwood created from parts of Newark and Ashfield, resulting in major changes to these two continuing seats.
Although the number of seats was unchanged and boundary changes were moderate, only Mid Bedfordshire was retained as a constituency name.
Modest changes to Cambridge, Peterborough and Isle of Ely, which was renamed North East Cambridgeshire.
Two additional constituencies: Billericay comprised a significant part of Basildon, together with areas transferred from Thurrock; and Rochford was formed primarily from the abolished constituency of Maldon, together with parts of Chelmsford and South East Essex (consequently renamed Castle Point).
Chester-le-Street was abolished, with the majority of the seat being included in the new constituency of North Durham and parts in Blaydon, and Houghton and Washington in Tyne and Wear.
Wansbeck was re-established (albeit with significantly different boundaries to previous versions), largely replacing Morpeth.
No changes to Carlisle, Whitehaven (renamed Copeland) and Workington, while Penrith and The Border gained a small part of Westmorland.
The creation of the new metropolitan county resulted in significant changes throughout the area, with very few constituencies bearing a close resemblance to the existing configuration of seats.
Cheadle and Hazel Grove were retained, subject to moderate adjustments, with part of the former being included in the new constituency of Tatton in Cheshire.
To compensate, Lancaster gained a small part of North Fylde, with the remainder of that constituency forming Wyre.
West Lancashire was formed from parts of the abolished constituencies of Ormskirk and Ince (see Greater Manchester).
There were further changes of varying degrees to Buckingham and the other four seats of Aylesbury, Beaconsfield, Chesham and Amersham, and Wycombe.
Small transfer from Sevenoaks to Dartford to make their electorates more equal and minor or no changes to Ashford, Faversham, Folkestone and Hythe, Gillingham, Tonbridge and Malling, and Tunbridge Wells.
Moderate changes involving Dorking (renamed Mole Valley), Epsom and Ewell, Esher and Reigate.
South Gloucestershire abolished, with part being added to Bristol North West and remainder forming the new seat of Northavon.
The majority of the continuing seat of Wells formed the basis of the new constituency of Somerton and Frome, which also included part of Yeovil.
Parts of Kidderminster (renamed Wyre Forest) were transferred to Leominster and a small area from South Worcestershire to Worcester to make the electorates more equal.
There were transfers from The Wrekin to Ludlow and Oswestry (renamed North Shropshire) to make the electorates more equal.
The majority of North Warwickshire was formed from a substantial part of Meriden (see West Midlands) and also included the town of Bedworth, transferred from Nuneaton.
Boothferry was created from parts of the abolished constituencies of Howden, Goole (see South Yorkshire) and Gainsborough (see Lincolnshire).
Selby was primarily formed from parts of the abolished constituencies of Barkston Ash (see West Yorkshire) and Howden (see Humberside).
Barkston Ash was abolished and primarily split between the new seats of Elmet and Selby (see North Yorkshire).
Abertillery, Bedwellty and Ebbw Vale were largely replaced by Blaenau Gwent and Islwyn, with small parts being included in Caerphilly, and Merthyr Tydfil and Rhymney (see Mid Glamorgan).
