Scottish Westminster constituencies wereScottishconstituencies of theHouse of Commons of theParliament of Great Britain, normally at thePalace of Westminster, from 1708 to 1801, and have been constituencies of the House of Commons of theParliament of the United Kingdom, also at Westminster, since 1801. Constituency boundaries have changed on various occasions, and are now subject to both periodical and ad hoc reviews of theBoundary Commission for Scotland.
Since 1950 each Scottish constituency has been either aburgh constituency or acounty constituency, defined by geographic boundaries and representing a seat for oneMember of Parliament (MP). Prior to 1950, there were alsouniversity constituencies and constituencies representing two or three parliamentary seats.
Scottishlocal governmentcounties andburghs were abolished in 1975. A burgh constituency is now one with a predominantly urban electorate, and a county constituency is one with more than a token rural electorate.
Counties and burghs were replaced with two-tierregions and districts and unitaryislands council areas, and the regions and districts were replaced with unitarycouncil areas in 1996.
The history of constituency boundaries can be divided into 12 distinct periods, as below, each starting with the date of ageneral election when a new set of boundaries was first used.
As a result of the union of Scotland withEngland andWales and the creation of the Parliament of Great Britain in 1707, Scotland had 48 constituencies representing seats for 45 MPs in the House of Commons of the newparliament at Westminster. Westminster was previously the meeting place for theParliament of England, which covered both England and Wales.
Scottish Westminster constituencies were first used in the1708 general election. Prior to that election Scotland was represented in the new parliament by MPs who were co-opted as commissioners of the formerParliament of Scotland.
In the Parliament of Great Britain, Scotland had 15 burgh constituencies and 33 county constituencies, with each representing a seat for one MP. The county constituencies included, however, three pairs of alternating constituencies, so that only one member of a pair was represented at any one time. Therefore, Scotland had more constituencies than seats. With the exception ofEdinburgh, the burgh constituencies consisted ofdistricts of burghs.
1708 boundaries were used for all subsequent elections of the Parliament of Great Britain.
The creation of the Parliament of the United Kingdom in 1801 was a merger of theParliament of Ireland with the Parliament of Great Britain. The first general election of this new parliament was thegeneral election of 1802, and there was at that stage no change to the boundaries of any pre-existing Westminster constituency.
1802 boundaries were used also in the general elections of1806,1807,1812,1818,1820,1826,1830 and1831.
For the1832 general election, Scottish Westminster constituencies were redefined by theRepresentation of the People (Scotland) Act 1832.
As a result of the legislation, there were 21 burgh constituencies and 30 county constituencies. Except forEdinburgh andGlasgow, which were two-seat constituencies, each Scottish constituency represented a seat for one MP. Therefore, Scotland had 53 parliamentary seats.
The constituencies related nominally to counties and burghs, but boundaries for parliamentary purposes were not necessarily those for other purposes. 14 of the burgh constituencies were districts of burghs.
1832 boundaries were used also in thegeneral elections of1835,1837,1841,1847,1852,1857,1859 and1865.
For the1868 general election Scottish Westminster constituencies were redefined by theRepresentation of the People (Scotland) Act 1868. For the samegeneral election, boundaries inEngland were redefined by theRepresentation of the People Act 1867 and there was, effectively, a transfer of seven parliamentary seats from England to Scotland.
As a result of the legislation, Scotland had 22 burgh constituencies, 32 county constituencies and two university constituencies. Except forEdinburgh,Dundee andGlasgow, each Scottish constituency represented a seat for one MP. Edinburgh and Dundee represented two seats each, and Glasgow represented three seats. Therefore, Scotland was entitled to 60 MPs.
The constituencies again related nominally to counties and burghs but, again, boundaries for parliamentary purposes were not necessarily those for other purposes.
1868 boundaries were used also in the general elections of1874 and1880.
TheRedistribution of Seats Act 1885 redefined the boundaries ofEnglish, Scottish andWelsh constituencies, and the new boundaries were first used in the1885 general election. The boundaries ofIrish constituencies were not affected.
In Scotland, as a result of the legislation, there were 32 burgh constituencies, 37 county constituencies and two university constituencies. Except forDundee, which was a two-seat constituency, each Scottish constituency represented a seat for one MP. Therefore, Scotland had 72 parliamentary seats.
The 1885 legislation detailed boundary changes but did not detail boundaries for all constituencies. For a complete picture of boundaries in Scotland, it has to be read in conjunction with the Representation of the People (Scotland) Act 1832 and the Representation of the People (Scotland) Act 1868.[1]
As under legislation of 1832 and 1868, constituencies related nominally to counties and burghs, but boundaries for parliamentary purposes were not necessarily those for other purposes. Also, boundaries for other purposes were altered by theLocal Government (Scotland) Act 1889 and by later related legislation.
1885 boundaries were used also in the general elections of1886,1892,1895,1900,1906,January 1910 andDecember 1910.
TheRepresentation of the People Act 1918 redefined constituency boundaries in relation to local government boundaries of the time, and the new constituency boundaries were first used in the1918 general election.
Scotland had 32 burgh constituencies, 38 county constituencies and one university constituency. One burgh constituency,Dundee, represented seats for two MPs, and the university constituency,Combined Scottish Universities, represented seats for three MPs. Each of the others elected one MP. Therefore, the legislation provided parliamentary seats for a total of 74 Scottish MPs.[1]
1918 boundaries were used also in the general elections of1922,1923,1924,1929,1931,1935 and1945.
For the1950 general election, under theRepresentation of the People Act 1948 and theHouse of Commons (Redistribution of Seats) Act 1949, Scotland had 32 burgh constituencies and 39 county constituencies, with each electing one MP. Therefore, Scotland had 71 parliamentary seats.[1]
Each constituency was entirely within a county or a grouping of two counties, or was if the cities ofAberdeen,Dundee,Edinburgh andGlasgow are regarded as belonging, respectively to thecounty of Aberdeen, thecounty of Angus, thecounty of Midlothian and thecounty of Lanark.[1]
For the1951 general election there were changes to the boundaries of six Scottish constituencies, but there was no change to county groupings, to the total numbers of constituencies and MPs, or to constituency names.[1]
The results of the First Periodical Review became effective for the1955 general election.[1]
The review defined 32 burgh constituencies and 39 county constituencies, with each electing one MP. Therefore, Scotland had 71 parliamentary seats.[1]
Each constituency was entirely within a county or a grouping of two or three counties, or was if the cities ofAberdeen,Dundee,Edinburgh andGlasgow are regarded as belonging, respectively to thecounty of Aberdeen, thecounty of Angus, thecounty of Midlothian and thecounty of Lanark.[1]
1955 boundaries were used also for the general election of1959.
There were changes to the boundaries of nine Scottish constituencies for the1964 general election but there was no change to county groupings, to the total numbers of constituencies and MPs, or to constituency names.[1]
1964 boundaries were used also for the1966 and1970 general elections.
The results of the Second Periodical Review, concluded in 1969, and of a subsequent interim review, concluded in 1972, became effective for theFebruary 1974 general election.
The reviews defined 29 burgh constituencies and 42 county constituencies, with each electing one MP. Therefore, Scotland had 71 parliamentary seats.[1][2]
Each constituency was entirely within a county or a grouping of two or three counties.[1][2]
February 1974 boundaries were used also in theOctober 1974 and1979 general elections.
The results of the Third Periodical Review became effective for the1983 general election.
The review defined 30 burgh constituencies and 42 county constituencies, with each electing one MP. Therefore, Scotland had 72 parliamentary seats.[3]
In 1975, Scottish counties and burghs had been abolished for local government purposes, under theLocal Government (Scotland) Act 1973, and the Third Periodical Review took account of new local government boundaries, which defined two-tier regions and districts and unitary islands council areas. No new constituency straddled a regional boundary, and no islands council area was divided between two constituencies.[3]
The boundary commission was required to designate each new constituency as eitherburgh orcounty but had no predetermined basis on which to do so. The commission took the view that each constituency with more than a token rural electorate would be a county constituency, and others, predominantly urban, would be burgh constituencies.[3]
1983 boundaries were used also in the1987 and1992 general elections.

The results of the Fourth Periodical Review of theBoundary Commission for Scotland became effective, as a result ofOrder in Council SI 1995 No 1037 (S.90),[4] for the1997 general election.
The review defined 28 burgh constituencies and 44 county constituencies, with each electing one MP. Therefore, Scotland had 72 parliamentary seats.[5]
Constituencies were defined in reference to the boundaries of local government regions and districts and islands areas effective on 1 June 1994, and each constituency was entirely within a region or a grouping of two or entirely within an islands area or a grouping of two. However, under theLocal Government etc (Scotland) Act 1994, the regions and districts were abolished in favour of newcouncil areas in 1996, the year before the new constituencies were first used in an election.
1997 boundaries were used also in the2001 general election.
The results of the Fifth Periodical Review became effective in Scotland for the2005 general election.
The review defined 19 burgh constituencies and 40 county constituencies, with each electing one MP. Therefore, Scotland had 59 parliamentary seats.
Each constituency was entirely within a council area or a grouping of two or three council areas.
The results of the2023 review of Westminster constituencies became effective in Scotland for the2024 general election.
The review defined 17 burgh constituencies and 40 county constituencies, with each electing one MP. Therefore, Scotland has 57 parliamentary seats.[6][7]
