It was the sixth [[Devolution in the United Kingdom|devolved]] [[general election]] since the Senedd (formerly the National Assembly for Wales) was established in 1999. The election was held alongside the [[2021 Scottish Parliament election|Scottish Parliament election]], [[2021 United Kingdom local elections|English local elections]], [[2021 London Assembly election|London Assembly]] and [[2021 London mayoral election|mayoral election]] and the [[2021 Hartlepool by-election|Hartlepool by-election]].

It was the first election in which 16- and 17-year-olds and legally resident foreign nationals were allowed to vote in Wales, the largest extension of the franchise in Wales since 1969. Both changes were a result of the [[Senedd and Elections (Wales) Bill 2019|Senedd and Elections (Wales) Act 2020]].<ref name=":assemblywales2">{{cite web|url=https://senedd.wales/senedd-now/news/16-and-17-year-olds-get-right-to-vote-a-historic-day-for-democracy-in-wales/|title=16 and 17-year olds get right to vote - a historic day for democracy in Wales|date=27 November 2019|website=senedd.wales|language=en-GB|access-date=24 December 2019}}</ref> It was also the first election for the legislature under its new name – 'Senedd Cymru' or 'the Welsh Parliament' – and thus this election may be called the '''2021 Welsh Parliament election''',<ref>{{Cite news|last1=Voce|first1=Antonio|last2=Leach|first2=Anna|last3=Clarke|first3=Seán|last4=Kommenda|first4=Niko|title=2021 election: latest results from Scottish, Welsh and local votes|language=en-GB|work=The Guardian|url=https://www.theguardian.com/politics/ng-interactive/2021/may/06/2021-elections-results-may-local-scottish-welsh-polls|date=2021-05-06|access-date=2021-05-08|issn=0261-3077}}</ref><ref>{{Cite web|title=Welsh Parliament election 2021|url=https://www.bbc.co.uk/news/topics/cqwn14k92zwt/welsh-parliament-election-2021|access-date=2021-05-08|website=BBC News|language=en-GB}}</ref> or '''2021 Senedd Cymru election''',<ref>{{Cite web|title=Senedd Cymru Elections - Ceredigion County Council|url=http://www.ceredigion.gov.uk/your-council/voting-elections/senedd-cymru-elections/|access-date=2021-05-09|website=www.ceredigion.gov.uk}}</ref><ref>{{Cite web|title=Senedd Cymru Elections|url=https://www.carmarthenshire.gov.wales/home/council-democracy/elections-voting/senedd-cymru-elections/#.YJhHFbX0mUk|access-date=2021-05-09|website=www.carmarthenshire.gov.wales}}</ref> in preference over the shorter name.

Five parties had [[Member of the Senedd|Members of the Senedd]] (MSs, formerly Assembly Members – AMs) elected at the previous election: [[Welsh Labour]], the [[Welsh Conservatives]], [[Plaid Cymru]], the [[UK Independence Party]] (UKIP), and the [[Welsh Liberal Democrats]]. Seven political parties were represented in the Senedd prior to the election. These are the five aforementioned parties and two parties that gained MSs who were elected for – and moved from – other political parties. The [[Abolish the Welsh Assembly Party]] gained two MSs who were elected for UKIP in 2016, and [[Propel (political party)|Propel]] (previously the Welsh Nation Party) gained an MS elected for Plaid Cymru in 2016.

The governing Labour Party's share of the constituency vote increased by over 5%, and the regional vote by over 4%, with thirty Labour MSs elected accounting for exactly half of the sixty seats, one more than in [[2016 National Assembly for Wales election|2016]] but one short of an overall majority and remaining as the largest party. The Conservatives became the Senedd's second-largest party and the [[Leader of the Opposition in Wales|official opposition]] to the Welsh Government with sixteen MSs elected, five more than their 2016 result. This result is the best that the Conservatives managed to achieve since the Senedd was established. Plaid Cymru slipped down to third place with thirteen MSs elected, one more than in 2016. [[Coalition government|Coalition partner]], the Liberal Democrats lost their single constituency seat from 2016, but gained a regional list seat, keeping their total of one seat, the same as in 2016. UKIP received no seats, down from their seven in the 2016 election. This included seats later transferred to Abolish the Welsh Assembly, who also received no seats.

Voter turnout was 46.6%, a record for a Senedd election.<ref name="Grey">{{cite news|last=Grey|first=Jack|date=16 May 2021|title=Welsh election: Votes low compared to Westminster and Scotland|publisher=[[BBC News]]|url=https://www.bbc.com/news/uk-wales-politics-57085775|access-date=25 July 2021}}</ref><ref>{{Cite web|title=Welsh Parliament (Senedd Cymru) turnout rate 2021|url=https://www.statista.com/statistics/284390/welsh-assembly-elections-turnout-rates/|date=2021-07-09|last=Clark|first=D.|access-date=2021-07-25|website=Statista|language=en}}</ref><ref>{{cite web|url=https://research.senedd.wales/research-articles/election-2021-how-many-people-voted/|title=Election 2021: how many people voted?|last1=Morgan|first1=Lucy|last2=Thomas|first2=Gareth|last3=Davies|first3=Owain|last4=Wilkes|first4=Joe|date=18 May 2021|website=senedd.wales|access-date=24 July 2021|language=en-GB|archive-date=24 July 2021|archive-url=https://web.archive.org/web/20210724233257/https://research.senedd.wales/research-articles/election-2021-how-many-people-voted/|url-status=dead}}</ref>

==Electoral system==
{{main|Mixed-Member Proportional|Additional Member System}}
In elections for the Senedd, using the [[additional member system]], each voter has two votes. The first vote is for a member for the voter's constituency, elected by the [[first past the post]] system. The second vote is for a regional [[closed list|closed party list]] of candidates. Additional member seats are allocated from the lists by the [[D'Hondt method]], with constituency results being taken into account in the allocation. In this election the system achieved a broadly proportional result in the [[North Wales (Senedd electoral region)|North Wales]] and [[Mid and West Wales (Senedd electoral region)|Mid and West Wales]] electoral regions. However, as in previous elections, the large number of constituency seats won by the Labour Party in the [[South Wales West (Senedd electoral region)|South Wales West]], [[South Wales Central (Senedd electoral region)|South Wales Central]] and [[South Wales East (Senedd electoral region)|South Wales East]] electoral regions, when set against the small proportion of available additional regional seats, means that the Labour Party is over-represented by a margin of four seats, when considered on a [[proportional representation|proportional]] basis.

Under the [[Wales Act 2014]], a candidate is allowed to stand in both a constituency and a regional list. However, holding a [[dual mandate]] with the House of Commons is illegal, meaning a Member of the Senedd cannot also be an MP.

This was the first election where 16- and 17-year olds could vote, following the enactment of [[Senedd and Elections (Wales) Act 2020|Senedd and Elections (Wales) Act]] in January 2020.<ref name=":assemblywales2"/>

The registration deadline for voters in this election was 11:59&nbsp;pm, 19 April 2021.<ref>{{cite web |url= https://www.gov.uk/register-to-vote |title= Register to vote |website= GOV.UK |access-date= 24 March 2021}}</ref>

==Background==
The [[2019 European Parliament election in the United Kingdom]] was the last of its kind. The newly formed [[Brexit Party]] came out on top in [[Wales (European Parliament constituency)|Wales]]. [[Plaid Cymru]], who support full [[Welsh independence]], came second, marking the first time it had beaten Labour in a Wales-wide election.<ref>{{cite news|url=https://www.bbc.com/news/uk-wales-politics-48417474|title=Brexit Party tops European poll in Wales|work=BBC News |date=27 May 2019}}</ref> The Brexit Party also formed a parliamentary group in the Assembly made up of the four ex-[[UK Independence Party]] (UKIP) members, led by [[Mark Reckless]].<ref>{{Cite news|url=https://www.bbc.com/news/uk-wales-politics-48275830|title=Assembly members join forces with Farage|date=15 May 2019|work=BBC News|access-date=25 March 2020|language=en-GB}}</ref> A [[snap election|snap]] [[2019 United Kingdom general election|general election in the United Kingdom]] was held on [[2019 United Kingdom general election in Wales|12 December 2019]]. [[Welsh Labour]] suffered an 8% drop in their vote, losing all their seats in [[North Wales]], except for [[Alyn and Deeside (UK Parliament constituency)|Alyn and Deeside]]. Labour ended up losing six parliamentary seats to the [[Welsh Conservatives]] in [[Boris Johnson]]'s [[landslide victory]]. These seats included [[Bridgend (UK Parliament constituency)|Bridgend]], which has been represented on the [[Bridgend (Senedd constituency)|assembly level]] by former [[First Minister of Wales]] [[Carwyn Jones]] since the [[1999 National Assembly for Wales election|1999 election]]. The Conservatives also picked up [[Brecon and Radnorshire (UK Parliament constituency)|Brecon and Radnorshire]] from the [[Welsh Liberal Democrats]].<ref>{{cite news|url=https://www.bbc.com/news/election-2019-50766203|title=Tories claim big scalps in Wales election results|work=BBC News |date=13 December 2019}}</ref>

On 31 January 2020, the United Kingdom [[Brexit|left]] the [[European Union]]. This followed a [[2016 United Kingdom European Union membership referendum|referendum]] on the matter in which Wales narrowly voted to leave the EU.<ref name="guard">{{cite news|url=https://www.theguardian.com/uk-news/2019/sep/22/english-people-wales-brexit-research|title=English people living in Wales tilted it towards Brexit, research finds|first=Frances|last=Perraudin|newspaper=The Guardian |date=22 September 2019|via=www.theguardian.com}}</ref> [[South Wales]] has been highlighted by many as evidence that Brexit cut across traditional party allegiances, as the area typically votes overwhelmingly for Labour.

==Turnout==
This election saw the highest ever turnout for a Senedd election, with 46.6% of eligible Welsh voters casting their ballot.<ref name="Grey"/> The previous high was 46.3% in 1999.<ref name="Grey"/> There were, however, also noticeable differences in turnout in certain constituencies, with 52% of registered voters voting in Dwyfor Meirionnydd and just 35% doing so in Merthyr Tydfil and Rhymney.<ref>{{cite web|last=Hayward|first=Will|date=7 May 2021|title=The voter turnout figures for every constituency in Wales|url=https://www.walesonline.co.uk/news/politics/senedd-parliament-voter-turnout-election-20553006|website=WalesOnline|access-date=28 October 2021|language=en}}</ref>

Dr Jac Larner, a politics lecturer at [[Cardiff University]] and an investigator for the Welsh election survey, said that the two largest factors in determining voter turnout between constituencies were their socio-economic make-up and the competitiveness of the seat. "Basically, people with higher levels of formal education, people who own houses, people with more wealth essentially, are more likely to turn up to vote," he told [[BBC News]]. "Straight away, as you compare Cardiff North to Merthyr Tydfil, you see big differences there. However, we also know there's a pretty strong relationship between how competitive a constituency is and turnout. That's not just in Wales, that's a general rule almost everywhere in the world - and Merthyr Tydfil, as we've seen in this election, is not competitive in any sense."<ref name="Grey"/>

Writing in [[Tribune (magazine)|''Tribune'' magazine]], Labour MS [[Mick Antoniw]] said that Welsh Labour's victory was "linked to the successful way in which Mark Drakeford and his government have handled the Covid pandemic and the way he has stood up to the more bizarre and reckless decisions of [[Boris Johnson]], always putting the safety of the Welsh people and Welsh interests first."<ref>{{cite web|url=https://tribunemag.co.uk/2021/05/why-welsh-labour-won|title=Why Welsh Labour Won|last=Antoniw|first=Mick|date=10 May 2021|work=Tribune|access-date=1 February 2022}}</ref>
