TheFirst periodic review of Scottish Parliament boundaries was carried out by theBoundary Commission for Scotland. It was announced on 3 July 2007 that the review was taking place.[1] Provisional proposals were published on 14 February 2008[2][3] and the final proposals were published on 26 May 2010. The new constituencies and regions were used for the first time at the2011 Scottish Parliament election.
TheScottish Parliament (Constituencies) Act 2004 requires the commission to review boundaries of all constituencies exceptOrkney andShetland (which cover, respectively, theOrkney Islands council area and theShetland Islands council area) so that the area covered by the reviewed constituencies will continue to be covered by a total of 71 constituencies.
The Orkney and Shetland constituencies were taken into account, however, in review of boundaries of the additional member regions.
Final recommendations followed public consultations and a series of local inquiries, and the terms of the 2004 act required final recommendations to be submitted in a report to theSecretary of State for Scotland.
Asecond review should have taken place within 12 years of the last; however, by the time of the2021 Scottish Parliament election this had not taken place. A meeting of the Boundary Commission in 2017 indicated that an extension would be sought by the Scottish Government to have the constituencies reviewed by the time of the next proposed election in 2025 (now 2026).[4]
The second review commenced in September 2022 and is planned to be completed by May 2025 before thenext scheduled election.[5]
For the purposes of the review the Boundary Commission for Scotland must take into account the boundaries of thelocal governmentcouncil areas. In order to do this some council areas were grouped together; the largest of these groupings of provisional proposals consisted of four of Scotland's 32 council areas, and the smallest only containing one. Constituencies created in 1999 were based onScottish Westminster constituencies that were created in 1997 and were based on the boundaries oflocal governmentregions and districts andislands areas that existed at that time but have since been abolished and replaced with the council areas.
Following the provisional proposal stages the Commission published their Final Recommendations. All the review processes were completed with the outlined constituencies below.
