Local Government Act 1972

The Local Government Act 1972 (1972 c. 70) is an Act of Parliament in the United Kingdom, that reformed local government in England and Wales, on 1 April 1974.
Its pattern of two-tier councils remains in use today in large parts of England, although the metropolitan county councils were abolished in 1986 and it was replaced with unitary authorities in many areas in the 1990s. In Wales, it established a similar pattern of counties and districts. These have since been entirely replaced with a system of unitary authorities. In Scotland, the Local Government (Scotland) Act 1973 established a similar system of two-tier regions and districts in 1975 - this was also replaced by a system of unitary council areas in 1996.
Elections were held to the new authorities in 1973, and they acted as 'shadow authorities' until the handover date. Elections to county councils were held on April 12, for metropolitan and Welsh districts on May 10 for non-metropolitan district councils on June 7.

Non-metropolitan districts
The Local Government Boundary Commission originally proposed 278 non-metropolitan districts in April 1972 (still working with the county boundaries found in the Bill). A further eighteen districts were added in the final proposals of November 1972, which were then ordered.
The splits were as follows (in most cases the splits were not exact, and many other changes to the borders of the districts took place at this time)
Devon: Torridge/North Devon
Dorset : Weymouth and Portland/Purbeck, North Dorset/East Dorset
Durham : Wear Valley/Teesdale
Hereford and Worcester : Hereford/South Herefordshire/Leominster
Humberside: Holderness/North Wolds
Isle of Wight: South Wight/Medina
Lancashire: Hyndburn/Rossendale
Leicestershire : Rutland/Melton, Harborough/Oadby and Wigston
Lincolnshire: Boston/South Holland
Northamptonshire: Daventry/South Northamptonshire
Northumberland : Berwick-upon-Tweed/Alnwick
Shropshire : Oswestry/North Shropshire, Bridgnorth/South Shropshire
Somerset: Taunton Deane/West Somerset
Suffolk: Forest Heath
The new district in Suffolk was necessitated by the decision to keep Newmarket in Suffolk; which would otherwise have become part of the South Cambridgeshire district.
Isles of Scilly
Section 265 af the Act allowed for the continuation of the local government arrangements for the Isles of Scilly. The Isles of Scilly Rural District Council became the Council of the Isles of Scilly, and certain services were to continue to be provided by Cornwall County Council as provided by order in council made by the Secretary of State, although the Isles were not technically in Cornwall before or after 1974.
Wales
Elections
Elections were held to the new authorities on three different Thursdays in 1973. Each new county and district was divided into electoral divisions. For county councils, each electoral division elected one member; for metropolitan district councils, each ward elected three members; and wards in non-metropolitan districts could elect a varying number of members. There was not sufficient time to conduct a full warding arrangement so a temporary system was used: in some county councils electoral divisions elected multiple councillors.
