Five constituencies cover Dyfed, also used for elections to the Senedd. The current boundaries have been effective since the 2007 Welsh Assembly election and the 2010 United Kingdom general election. [1] [n 1]
Dyfed is one of the eight preserved counties of Wales, consisting of the principal areas of Pembrokeshire, Carmarthenshire and Ceredigion. These principal areas are also known as counties.
For Senedd elections, constituencies are grouped into additional member electoral regions.

The Boundary Commission for Wales submitted their final proposals in respect of the Sixth Periodic Review of Westminster Constituencies (the 2018 review) in September 2018. Although the proposals were immediately laid before Parliament they were not brought forward by the Government for approval. Accordingly, they didnot come into effect for the 2019 election which took place on 12 December 2019, and which was contested using the constituency boundaries in place since 2010.
Under the terms of the Parliamentary Voting System and Constituencies Act 2011, the Sixth Review was based on reducing the total number of MPs from 650 to 600 and a strict electoral parity requirement that the electorate of all constituencies should be within a range of 5% either side of the electoral quota.
On 24 March 2020, the Minister of State for the Cabinet Office, Chloe Smith, issued a written statement to Parliament setting out the Government's thinking with regard to parliamentary boundaries. They propose to bring forward primary legislation to remove the statutory obligation to implement the 2018 Boundary Review recommendations, as well as set the framework for future boundary reviews in time for the next review which is due to begin in early 2021 and report no later than October 2023. It is proposed that the number of constituencies now remains at the current level of 650, rather than being reduced to 600, while retaining the requirement that the electorate should be no more than +/- 5% from the electoral quota.

The Senedd, officially known as the Welsh Parliament in English and Senedd Cymru in Welsh, is the devolved, unicameral legislature of Wales. A democratically elected body, it makes laws for Wales, agrees certain taxes and scrutinises the Welsh Government. It is a bilingual institution, with both Welsh and English being the official languages of its business. From its creation in May 1999 until May 2020, the Senedd was known as the National Assembly for Wales.
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:
As a result of the Fifth Periodical Review of the Boundary Commission for Scotland, Scotland is covered by 59 constituencies of the House of Commons of the United Kingdom Parliament - 19 Burgh constituencies and 40 County constituencies. Constituencies marked * appear on the Central Area Enlargement.
Arfon is a constituency in Wales represented in the House of Commons of the UK Parliament at Westminster. Although it is relatively large by geographical area, the constituency is a predominantly urban rather than rural seat, with the majority of the population living in the two towns of Bethesda and Caernarfon, as well as in the city of Bangor, on which the constituency is based. "Arfon" is a historical name for the area, meaning "facing Anglesey"; it is also the name of the former district council. This seat was created by the Welsh Boundary Commission in time for the 2010 general election; it replaced the old seat of Caernarfon. Bangor was in the old seat of Conwy. The same boundaries were used for the Arfon Welsh Assembly constituency in the 2007 Welsh Assembly election.
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 are not used for local government.
There are four types of elections in Wales: elections to the House of Commons of the United Kingdom, elections to the devolved Senedd, local elections to the 22 principal areas, and the Police and Crime Commissioner elections, in addition to by-elections for each aforementioned election. Elections are held on Election Day, which is conventionally a Thursday. Since the passing of the Fixed-term Parliaments Act 2011 for UK general elections, all four types of elections are held after fixed periods, though early elections to the UK parliament can occur in certain situations, with Senedd elections being postponed to avoid elections to the UK parliament and Senedd coinciding with each other.
Carmarthen East and Dinefwr is a constituency of the Senedd. It elects one Member of the Senedd by the first past the post method of election. Also, however, it is one of eight constituencies in the Mid and West Wales electoral region, which elects four additional members, in addition to eight constituency members, to produce a degree of proportional representation for the region as a whole.
Llanelli is a constituency of the Senedd. It elects one Member of the Senedd by the first past the post method of election. Also, however, it is one of eight constituencies in the Mid and West Wales electoral region, which elects four additional members, in addition to eight constituency members, to produce a degree of proportional representation for the region as a whole.
Aberavon is a constituency of the Senedd. It elects one Member of the Senedd by the first past the post method of election. Also, however, it is one of seven constituencies in the South Wales West electoral region, which elects four additional members, in addition to seven constituency members, to produce a degree of proportional representation for the region as a whole.
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 2023 Periodic Review of Westminster constituencies is the current 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 is the successor to the 2018 Periodic Review of Westminster constituencies, which was ultimately abandoned after it failed to pass into law.
The next Senedd election is due to be held in or before May 2026 to elect 60 members to the Senedd. It will be the seventh devolved general election since the Senedd was established in 1999. It will also be the second election since the Senedd changed its name in May 2020.
