The Parliament Acts 1911 and 1949 are two Acts of the Parliament of the United Kingdom, which form part of the constitution of the United Kingdom. Section 2(2) of the Parliament Act 1949 provides that the two Acts are to be construed as one.
The boundary commissions in the United Kingdom are non-departmental public bodies responsible for determining the boundaries of constituencies for elections to the House of Commons. There are four boundary commissions:
Leicester South is a constituency, recreated in 1974, represented in the House of Commons of the UK Parliament since 2011 by Jonathan Ashworth of the Labour Co-op Party. A previous version of the seat existed between 1918 and 1950. Except for a 2004 by-election when it was won by the Liberal Democrats, Leicester South has been held by the Labour Party since 1987.
In the United Kingdom (UK), each of the electoral areas or divisions called constituencies elects one member to the House of Commons.
East Yorkshire is a county constituency for the House of Commons of the Parliament of the United Kingdom. It elects one Member of Parliament (MP) at least once every five years by the first-past-the-post electoral system. The constituency has been represented by Greg Knight of the Conservative Party since the 2001 general election.
Kingston upon Hull West and Hessle is a borough constituency for the House of Commons of the Parliament of the United Kingdom. It elects one Member of Parliament (MP) at least once every five years by the first-past-the-post electoral system. The constituency has been represented by Emma Hardy of the Labour Party since the 2017 general election.
The Representation of the People Act 1949 was an Act of the Parliament of the United Kingdom. The Act consolidated previous electoral law, but also made some changes to administration. Representation of the People amendments followed in 1969, 1977, 1978, and 1980, all being repealed through consolidation into the Representation of the People Act 1983.
The Parliament of the United Kingdom currently has 650 parliamentary constituencies across the constituent countries, each electing a single member of parliament (MP) to the House of Commons by the plurality voting system, ordinarily every five years. Voting last took place in all 650 of those constituencies at the United Kingdom general election on 12 December 2019.
The Lieutenancies Act 1997 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.
Scottish Westminster constituencies were Scottish constituencies of the House of Commons of the Parliament of Great Britain, normally at the Palace of Westminster, from 1708 to 1801, and have been constituencies of the House of Commons of the Parliament 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 the Boundary Commission for Scotland.
The Senedd constituencies and electoral regions are the electoral districts used to elect Members of the Senedd to the Senedd, and have been used in some form since the first election of the then National Assembly for Wales in 1999. New boundaries were introduced for the 2007 elections and currently consist of forty constituencies and five regions. The five electoral regions are: Mid and West Wales, North Wales, South Wales Central, South Wales East, and South Wales West, with the forty constituencies listed below. Voting last took place in all districts in the 2021 Senedd election, and is not used for local government.
The Representation of the People Act 1985 is an Act of the Parliament of the United Kingdom concerning British electoral law.
The Fifth Periodic Review of Westminster constituencies was undertaken between 2000 and 2007 by the four boundary commissions for England, Scotland, Wales and Northern Ireland for the UK Parliament. The changes for England, Wales and Northern Ireland took effect at the 2010 United Kingdom general election; that for Scotland took effect at the 2005 election. All of the recommendations were approved.
The House of Commons Act 1949 was an Act of the Parliament of the United Kingdom that provided for the periodic review of the number and boundaries of parliamentary constituencies.
The Parliamentary Voting System and Constituencies Act 2011(c. 1) is an Act of the Parliament of the United Kingdom that made provision for the holding of a referendum on whether to introduce the Alternative Vote system in all future general elections to the UK Parliament and also made provision on the number and size of parliamentary constituencies. The Bill for the Act was introduced to the House of Commons on 22 July 2010 and passed third reading on 2 November by 321 votes to 264. The House of Lords passed the Bill, with amendments, on 14 February 2011, and after some compromises between the two Houses on amendments, it received Royal Assent on 16 February 2011.
The 2013 Periodic Review of Westminster constituencies, also known as the Sixth Review, or just boundary changes, was an ultimately unfruitful cycle of the process by which constituencies of the House of Commons of the United Kingdom are reviewed and redistributed. The four UK boundary commissions carried out their reviews between 2011 and 2013, but their recommendations were not taken up by the government and instead the 2018 Periodic Review of Westminster constituencies was carried out from 2016 to 2018. That review was also not implemented and its results were formally laid aside in 2020.
The Electoral Registration and Administration Act 2013 is an Act of the Parliament of the United Kingdom which amended electoral law in the United Kingdom. It introduced Individual Electoral Registration (IER).
The 2023 Periodic Review of Westminster constituencies was the most recent cycle of the process to redraw the constituency map for the House of Commons. The process for periodic reviews of parliamentary constituencies in the United Kingdom is governed by the Parliamentary Constituencies Act 1986, as amended by the Parliamentary Voting System and Constituencies Act 2011 and subsequently by the Parliamentary Constituencies Act 2020. This review was the successor to the 2018 Periodic Review of Westminster constituencies, which was ultimately abandoned after it failed to pass into law. Considering the abandonment of the previous reviews since 2015, the 2023 Periodic Review of Westminster constituencies is set to be the first successful review based on electoral registers drawn up using the Individual Electoral Registration model introduced from 2014–15, which has drawn criticism regarding being a measure to influence future boundary reviews in the Conservatives' favour.
The 2018 Periodic Review of Westminster constituencies was an ultimately unfruitful cycle of the process by which constituencies of the House of Commons of the United Kingdom are reviewed and redistributed. The four UK boundary commissions carried out their reviews between 2016 and 2018, but their recommendations were not taken up by the government and were formally laid aside in 2020.
This article covers the timeline of the most recent cycle of the process to redraw the constituency map for the House of Commons, namely the 2023 Periodic Review of Westminster constituencies. For a summary of the final outcome of the review, see 2023 Periodic Review of Westminster constituencies.
