The next Senedd election is due to be held by 7 May 2026^[1] to elect 96 members to the Senedd (Welsh Parliament; Welsh : Senedd Cymru). It will be the seventh devolved general election since the Senedd (formerly the National Assembly for Wales) was established in 1999. If held in 2026 it will also be the first election following current reforms to the voting system, which would increase the size of the Senedd from 60 members to 96, adopting a party-list voting system, reducing the number of constituencies to sixteen, and shortening its term from five years to four.^[2]^[3] It will also be the second election since the Senedd changed its name in May 2020.

Lee Waters	Llanelli	2016	Welsh Labour	24 October 2024^[6]
Dawn Bowden	Merthyr Tydfil and Rhymney	2016	Welsh Labour	17 January 2025^[7]
Mick Antoniw	Pontypridd	2011	Welsh Labour	24 January 2025^[8]
Joyce Watson	Mid and West Wales	2007	Welsh Labour	25 January 2025^[9]

Electoral system

In all prior elections since its establishment as the Welsh Assembly in 1999, the Senedd has been elected through the additional member system, under which 40 out of 60 seats were elected by the first past the post system from single-member constituencies (the same as those used for Westminster), while the remaining 20 were attributed regionally (in 5 regions of 4 seats) on the basis of a second vote for a closed party list of candidates. The additional member seats in each region were allocated from the lists by the D'Hondt method, with constituency results being taken into account in the allocation.

Following the approval of the Senedd Reform Act, the size of the Senedd will be increased from 60 to 96 MSs, all elected through closed party list proportional representation (using the D'Hondt method). The elections will be organised in 16 six-member constituencies created by pairing up the 32 redrawn Westminster constituencies.^[10]^[11]

Although the new system would only be ready and used for elections held after 6 April 2026, to allow time for the new constituencies to be drawn up.^[12] The next election is due to be held on 7 May 2026.^[13]

Another proposed reform bill would have provided for mandatory "zipping" of male and female candidates in the list to ensure that for every party, half of the Members will be women. However, this bill was scrapped in September 2024.^[14]

A member of the Senedd is a representative elected to the Senedd. There are sixty members, with forty members chosen to represent individual Senedd constituencies, and twenty to represent the five electoral regions of the Senedd in Wales.

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 to 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 officially known as the National Assembly for Wales and was often simply called the Welsh Assembly.

The first minister of Wales is the leader of the Welsh Government and keeper of the Welsh Seal. The first minister chairs the Welsh Cabinet and is primarily responsible for the formulation, development and presentation of Welsh Government policy. Additional functions of the first minister include promoting and representing Wales in an official capacity, at home and abroad, and responsibility for constitutional affairs, as they relate to devolution and the Welsh Government.

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.

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 community councils and the 22 principal areas, and the police and crime commissioner elections. In addition there are by-elections for each aforementioned election. Elections are held on Election Day, which is conventionally a Thursday. Three of these four types of elections are held after fixed periods; the exception is UK general elections, the timing of which is at the discretion of the prime minister of the United Kingdom. Senedd elections may be postponed to avoid elections to the UK parliament and Senedd coinciding with each other.
