The local government areas of Scotland were redefined by the Local Government (Scotland) Act 1973 and redefined again by the Local Government etc (Scotland) Act 1994. The 1973 Act created a system of nine two-tier regions and three islands areas, and this system completely replaced local government counties and burghs in 1975. The new regions were generally very different from the counties which had been in use since the Local Government (Scotland) Act 1889. Also, the districts were very different from the subdivisions of counties, also called districts, which had been in use since the Local Government (Scotland) Act 1929. Background The reorganisation of local government in Scotland was a matter of political debate from the mid-1960s. In June 1963 the Scottish Office published a white paper titled The Modernization of Local Government in Scotland (Cmnd.2067). This proposed a large decrease in the number of local authorities in the country. There was to be a reduction from thirty-three county councils to between ten and fifteen. At the same time, new "second-tier councils" were proposed, with burghs being merged with the surrounding "landward" rural areas. The minimum population for the areas of these councils was to be 40,000. It was hoped that the reforms could be carried out quickly, with existing authorities agreeing to amalgamation and boundary alterations prior to legislation being passed. The white paper was rejected by the Association of Large Burghs, and by the Scottish Labour Party. At the 1964 general election Labour came to power, and the scheme was not pursued. Instead a royal commission under the chairmanship of Lord Wheatley was appointed in 1966 to enquire into local administration. Wheatley commented that "Our terms of reference are far-reaching: we have a free hand to recommend whatever arrangement of authorities, boundaries and functions seem likely to be right for a long time to come". The commission's report was delivered on 25 September 1969, and recommended a two-tier system of 7 regions and 37 districts. The incoming Conservative government accepted the broad principles of the commission's report in their white paper Reform of Local Government in Scotland (Cmnd. 4583), published in February 1971. The number of regions was increased to 8, and of districts to 49. Also Orkney and Shetland were to become "most-purpose" authorities, separated from the Highland Region. Following consultation, the structure was modified. The Western Isles, which was to have formed four districts of the
