The Lieutenancies Act 1997 (c. 23) is an Act of Parliament in the United Kingdom that defines areas that lord-lieutenants are appointed to in Great Britain. It came into force on 1 July 1997. Creation of modern local government Prior to the Local Government Act 1888, a Lord-Lieutenant was appointed to each of the counties. However this Act redefined the areas to be combinations of the new administrative counties and county boroughs. In practice the effect was quite minor, with only a few border differences between the historic and new administrative counties. These areas changed little until the 1965 creation of Greater London and Huntingdon and Peterborough, which resulted in the abolition of the offices of Lord Lieutenant of Middlesex, Lord Lieutenant of the County of London and Lord Lieutenant of Huntingdonshire and the creation of the Lord Lieutenant of Greater London and Lord Lieutenant of Huntingdon and Peterborough. Local government re-organisation England In 1974 county boroughs and several administrative counties were rearranged in England and Wales. Lieutenancies were also redefined to use the new metropolitan and non-metropolitan counties directly. Many of the new Lieutenancies were not based on traditional counties in any way. Many of these Lieutenancies did not last long, however. By the mid-1990s, another local government reorganisation was underway and many of the non-metropolitan counties in England were re-organised, resulting in the creation of unitary authorities. At this time plans were drawn up for the Lieutenancies Act which would separate the Lieutenancy areas from being directly based on local government areas again. Although the term is not actually used in the Act, the areas it covers have come to be known as "ceremonial counties". Scotland The Local Government (Scotland) Act 1973 redefined the Lieutenancies not to be based on the then new Scottish Regions but as an approximation of the traditional counties in some places and entirely new creations in others. Local government in Scotland was further reformed on 1 Apr 1996 into single-tier authorities designated as "Councils" but the lieutenancies remain mostly matching the pre-1973 counties and cities. Wales Local government in Wales was reorganised into a single-tier system on 1 Apr 1996 with the authorities designated as "Principal Councils" but nominally described as Cities, Boroughs or Counties. The lieutenancy areas remain based on the system of local government existing from 1974 to 1996. Passage through Parliament The Lieutenancies Bill was introduced in the House of
