Plaid Cymru (English: / / PLYDE KUM-ree; Welsh: [plaid ˈkəmri]; officially Plaid Cymru – the Party of Wales, and often referred to simply as Plaid) is a centre-left to left-wing, Welsh nationalist political party in Wales, committed to Welsh independence from the United Kingdom.
Plaid was formed in 1925 and won its first seat in the UK Parliament in 1966. The party holds three of 40 Welsh seats in the UK Parliament, 12 of 60 seats in the Senedd, and 202 of 1,231 principal local authority councillors. It is a member of the European Free Alliance.
In September 2008, a senior Plaid assembly member spelled out her party's continuing support for an independent Wales. The then Welsh Minister for Rural Affairs, Elin Jones, told delegates at Plaid's annual conference in Aberystwyth that the party would continue its commitment to independence under the coalition with Welsh Labour.
In 2014, the party's constitution included the following aims:
- Securing Welsh independence in Europe
- Economic prosperity, social justice and a healthy natural environment with decentralist socialism
- A national community with equal citizenship and respect for diversity
- Develop a bilingual society
- Promote Wales to the world and achieve United Nations membership
While Wales remains part of the United Kingdom, Plaid Cymru want to see further powers devolved from the UK Government to Wales, including: broadcasting and communication powers, devolution of the Crown Estate, welfare and rail.
The party also favours lowering the voting age to 16 years old. The voting age has already been lowered to include 16- and 17-year-olds for both Senedd elections and local elections in Wales since 2020, but not for UK general elections or police and crime commissioner elections: 18 is the minimum voting age for both of these.
In 2022, Plaid Cymru's policies included in its co-operation agreement with Welsh Labour included:
- Free school meals for all primary school children
- Free childcare for all two-year-olds
- Commitment to deal with[clarification needed] second homes
- Creation of a national care service
- Long-term Senedd reform
- Reforming council tax
- Increased investment in flood defence and prevention
While both the Labour and Liberal parties of the early 20th century had accommodated demands for Welsh home rule, no political party existed for the purpose of establishing a Welsh government. Plaid Genedlaethol Cymru (English: The National Party of Wales) was formed on 5 August 1925, by Moses Gruffydd, H. R. Jones and Lewis Valentine, members of Byddin Ymreolwyr Cymru ("The Home Rule Army of Wales"; literally, "The Self-Rulers' Army of Wales"); and Fred Jones, Saunders Lewis and DJ Williams (David John Williams) of Y Mudiad Cymreig ("The Welsh Movement"). Initially, home rule for Wales was not an explicit aim of the new movement; keeping Wales Welsh-speaking took primacy, with the aim of making Welsh the only official language of Wales.
In the 1929 general election the party contested its first parliamentary constituency, Caernarvonshire, polling 609 votes, or 1.6% of the vote for that seat. The party contested few such elections in its early years, partly due to its ambivalence towards Westminster politics. Indeed, the candidate Lewis Valentine, the party's first president, offered himself in Caernarvonshire on a platform of demonstrating Welsh people's rejection of English dominion.
By 1932, the aims of self-government and Welsh representation at the League of Nations had been added to that of preserving Welsh language and culture. However, this move, and the party's early attempts to develop an economic critique, did not broaden its appeal beyond that of an intellectual and socially conservative Welsh language pressure group. The alleged sympathy of the party's leading members (including President Saunders Lewis) towards Europe's totalitarian regimes compromised its early appeal further.
Saunders Lewis, David John Williams and Lewis Valentine set fire to the newly constructed RAF Penyberth air base on the Llŷn Peninsula in Gwynedd in 1936, in protest at its siting in the Welsh-speaking heartland. The leaders' treatment, including the trial judge's dismissal of the use of Welsh and their subsequent imprisonment in Wormwood Scrubs, led to "The Three" becoming a cause célèbre. This heightened the profile of the party dramatically and its membership had doubled to nearly 2,000 by 1939.
Penyberth, and Plaid Cymru's neutral stance during the Second World War, prompted concerns within the UK Government that it might be used by Germany to insert spies or carry out other covert operations. In fact, the party adopted a neutral standpoint and urged (with only limited success) conscientious objection to war service.
In 1943 Saunders Lewis contested the University of Wales parliamentary seat at a by-election, gaining 1,330 votes, or 22%. In the 1945 general election, with party membership at around 2,500, Plaid Cymru contested seven seats, as many as it had in the preceding 20 years, including constituencies in south Wales for the first time. At this time Gwynfor Evans was elected president.
Gwynfor Evans's presidency coincided with the maturation of Plaid Cymru (as it now began to refer to itself) into a more recognisable political party. Its share of the vote increased from 0.7% in the 1951 general election to 3.1% in 1955 and 5.2% in 1959. In the 1959 election, the party contested a majority of Welsh seats for the first time. Proposals to flood the village of Capel Celyn in the Tryweryn valley in Gwynedd in 1957 to supply the city of Liverpool with water played a part in Plaid Cymru's growth. The fact that the parliamentary bill authorising the dam went through without support from any Welsh MPs showed that the MPs' votes in Westminster were not enough to prevent such bills from passing.
Support for the party declined slightly in the early 1960s, particularly as support for the Liberal Party began to stabilise from its long-term decline. In 1962 Saunders Lewis gave a radio talk entitled Tynged yr Iaith (The fate of the language) in which he predicted the extinction of the Welsh language unless action was taken. This led to the formation of Cymdeithas yr Iaith Gymraeg (the Welsh Language Society) the same year.
Labour's return to power in 1964 and the creation of the post of Secretary of State for Wales appeared to represent a continuation of the incremental evolution of a distinctive Welsh polity, following the Conservative government's appointment of a Minister of Welsh Affairs in the mid-1950s and the establishment of Cardiff as Wales' capital in 1955.
However, in 1966, less than four months after coming in third in the constituency of Carmarthen, Gwynfor Evans captured the seat from Labour at a by-election. This was followed by two further by-elections in Rhondda West in 1967 and Caerphilly in 1968 in which the party achieved massive swings of 30% and 40% respectively, coming within a whisker of victory. The results were caused partly by an anti-Labour backlash. Expectations in coal mining communities that the Wilson government would halt the long-term decline in their industry had been dashed by a significant downward revision of coal production estimates. However, particularly in Carmarthen, Plaid also successfully depicted Labour's policies as a threat to the viability of small Welsh communities.
In the 1970 general election Plaid Cymru contested every seat in Wales for the first time and its vote share surged from 4.5% in 1966 to 11.5%. Gwynfor Evans lost Carmarthen to Labour, but regained the seat in October 1974, by which time the party had gained a further two MPs, representing the constituencies of Caernarfon and Merionethshire.
Plaid Cymru's emergence (along with the Scottish National Party) prompted the Wilson government to establish the Kilbrandon Commission on the constitution. The subsequent proposals for a Welsh Assembly were, however, heavily defeated in a referendum in 1979. Despite Plaid Cymru's ambivalence toward home rule (as opposed to outright independence) the referendum result led many in the party to question its direction.
In 1975, Plaid Cymru opposed remaining in the European Communities (EC), feeling that the EC's regional aid policies would "reconcile places like Wales to their subordinate position". Nevertheless, 65% of Welsh voters voted to remain in the EC during a 1975 referendum. The EC were incorporated into the European Union (EU) in 1993.
At the 1979 general election the party's vote share declined from 10.8% to 8.1% and Carmarthen was again lost to Labour, although Caernarfon and Merionethshire were held by the party.
Caernarfon MP Dafydd Wigley succeeded Gwynfor Evans as president in 1981, inheriting a party whose morale was at an all-time low. In 1981 the party adopted "community socialism" as a constitutional aim. While the party embarked on a wide-ranging review of its priorities and goals, Gwynfor Evans fought a successful campaign (including the threat of a hunger strike) to oblige the Conservative government to fulfill its promise to establish S4C, a Welsh-language television station. In 1984 Dafydd Elis-Thomas was elected president, defeating Dafydd Iwan, a move that saw the party shift to the left. Ieuan Wyn Jones (later Plaid Cymru leader) captured Ynys Môn from the Conservatives in 1987. In 1989 Dafydd Wigley once again assumed the presidency of the party.
In the 1992 general election the party added a fourth MP, Cynog Dafis, when he gained Ceredigion and Pembroke North from the Liberal Democrats. Dafis was endorsed by the local branch of the Green Party. The party's vote share recovered to 9.9% at the 1997 general election.
In 1997, following the election of a Labour government committed to devolution for Wales, a further referendum was narrowly won, establishing the National Assembly for Wales. Plaid Cymru became the main opposition to the ruling Labour Party, with 17 seats to Labour's 28. In doing so, it appeared to have broken out of its rural Welsh-speaking heartland, and gained seats in traditionally strong Labour areas in industrial South Wales.
First National Assembly (1999–2003)
In the 1999 election Plaid Cymru gained seats in traditional Labour areas such as Rhondda, Islwyn and Llanelli, achieving by far its highest share of the vote in any Wales-wide election. While Plaid Cymru regarded itself as the natural beneficiary of devolution, others attributed its performance in large part to the travails of the Labour Party[who?], whose nomination for Assembly First Secretary, Ron Davies, was forced to stand down in an alleged sex scandal. The ensuing leadership battle, won by Alun Michael, did much to damage Labour, and thus aided Plaid Cymru, whose leader was the more popular and higher profile Dafydd Wigley. The Labour Party's UK national leadership was seen to interfere in the contest and deny the popular Rhodri Morgan victory. Less than two months later, in elections to the European parliament, Labour support slumped further, and Plaid Cymru came within 2.5% of achieving the largest share of the vote in Wales. Under the new system of proportional representation, the party also gained two MEPs.
Plaid Cymru then developed political problems of its own. Dafydd Wigley resigned, citing health problems but amid rumours of a plot against him. His successor, Ieuan Wyn Jones, struggled to impose his authority, particularly over controversial remarks made by a councillor, Seimon Glyn. At the same time, Labour leader and First Minister Alun Michael was replaced by Rhodri Morgan.
In the 2001 general election, notwithstanding Plaid Cymru recording its highest-ever vote share in a general election, 14.3%, the party lost Wyn Jones's former seat of Ynys Môn to Albert Owen, although it gained Carmarthen East and Dinefwr, where Adam Price was elected.
Second National Assembly (2003–07)
The Assembly elections of May 2003 saw the party's representation drop from 17 to 12, with the seats gained in the 1999 election falling again to Labour and the party's share of the vote declining to 21%. Plaid Cymru narrowly remained the second-largest party in the National Assembly ahead of the Conservatives, Liberal Democrats and Forward Wales.
On 15 September 2003 folk-singer and county councillor Dafydd Iwan was elected as Plaid Cymru's president. Ieuan Wyn Jones, who had resigned from his dual role as president and Assembly group leader following the losses in the 2003 Assembly election, was re-elected in the latter role. Elfyn Llwyd remained the Plaid Cymru leader in the Westminster Parliament. Under Iwan's presidency the party formally adopted a policy of independence for Wales within Europe.
The 2004 local election saw the party lose control of the two South Wales councils it gained in 1999, Rhondda Cynon Taff and Caerphilly, while retaining its stronghold of Gwynedd in the north-west. The results enabled the party to claim a greater number of ethnic minority councillors than all the other political parties in Wales combined, along with gains in authorities such as Cardiff and Swansea, where Plaid Cymru representation had been minimal. In the European Parliament elections of the same year, the party's vote share fell to 17.4%, and the reduction in the number of Welsh MEPs saw its representation reduced to one.
In the general election of 5 May 2005, Plaid Cymru lost the Ceredigion seat to the Liberal Democrats; this result was a disappointment to Plaid, who had hoped to gain Ynys Môn. Overall therefore, Plaid Cymru's Parliamentary representation fell to three seats, the lowest number for the party since 1992. The party's share of the vote fell to 12.6%.
Since Plaid Genedlaethol Cymru reformation to 'Plaid Cymru' in 1933, the logo representing the party was the green 'triban' (three peaks) which symbolically represented Plaid's three key goals; self-government, cultural prosperity and economic prosperity, 'anchored in the bedrock of Welsh identity and history that is the Welsh upland landscape', the logo would change in the late stages of 20th century to include the red dragon of Wales, however this version was short-lived. In 2006, the party voted constitutional changes to formally designate the party's leader in the assembly as its overall leader, with Ieuan Wyn Jones being restored to the full leadership and Dafydd Iwan becoming head of the voluntary wing of the party. 2006 saw the party unveil a radical change of image, opting to use "Plaid" as the party's name, although "Plaid Cymru — the Party of Wales" would remain the official title. Plaid would abandon the triban (apart from the merchandise) and adopt the yellow Welsh poppy (Meconopsis cambrica).
Third National Assembly (2007–2011)
In the National Assembly election of 3 May 2007, Plaid Cymru increased its number of seats from 12 to 15, regaining Llanelli, gaining one additional list seat and winning the newly created constituency of Aberconwy. The 2007 election also saw Plaid Cymru's Mohammad Asghar become the first ethnic minority candidate elected to the Welsh Assembly. The party's share of the vote increased to 22.4%.
After weeks of negotiations involving all four parties in the Assembly, Plaid Cymru and Labour agreed to form a coalition government. Their agreed "One Wales" programme included a commitment for both parties to campaign for a Yes vote in a referendum on full law-making powers for the Assembly, to be held at a time of the Welsh Assembly Government's choosing. Ieuan Wyn Jones was subsequently confirmed as Deputy First Minister of Wales and Minister for the Economy and Transport. Rhodri Glyn Thomas was appointed Heritage Minister. He later stood down, and Alun Ffred Jones took over. Ceredigion AM Elin Jones was appointed to the Rural Affairs brief in the new 10-member cabinet. Jocelyn Davies became Deputy Minister for Housing, and later, Regeneration.
Fourth National Assembly (2011–16)
In the 2011 National Assembly election Plaid slipped from second place to third, being overtaken by the Welsh Conservatives and losing its deputy leader Helen Mary Jones. The party held an inquiry into the election result. The internal investigation led to the adoption of wide-ranging changes to its constitution, including a streamlining of the leadership structure.
In May 2011, Ieuan Wyn Jones announced he would stand down as leader within the first half of the Assembly term. A leadership election was held in which three candidates eventually stood: Elin Jones, Dafydd Elis-Thomas and Leanne Wood; Simon Thomas withdrew his candidacy before ballots were cast.
On 15 March 2012, Plaid Cymru elected Leanne Wood as its new leader. She received 55% of the vote, over second-placed Elin Jones with 41%. Wood was the party's first female leader, and its first not to be a fluent Welsh speaker. Soon after her election as leader she appointed former MP Adam Price to head an economic commission for the party "focussed on bringing together tailor-made policies in order to transform our economy". On 1 May 2012, it was confirmed Leanne Wood would not be taking the £23,000 pay increase that every other party leader in the Assembly receives.
On 12 November 2012, Wood announced she would aim to abandon her relatively safe list seat by winning a constituency at the 2016 National Assembly elections; she later confirmed she would contest the Rhondda. Adam Price was subsequently selected as the party's candidate for Carmarthen East and Dinefwr. Lindsay Whittle confirmed he would stand solely in Caerphilly.
On 20 June 2013, former party leader Ieuan Wyn Jones stood down from the Assembly as the member for Ynys Môn. Plaid Cymru's candidate Rhun ap Iorwerth was elected as the new Assembly Member for the constituency, receiving 12,601 votes (a 58% share) with a majority of 9,166 over the Labour candidate.
Fifth National Assembly/Senedd (2016–2021)
At the 2016 Welsh Assembly elections, Plaid Cymru gained one seat, became the Assembly's second-largest party and briefly became the official opposition to the Welsh Government with 12 seats. By January 2018 Plaid Cymru had been reduced to ten Assembly Members, following the resignation of Dafydd Elis-Thomas in 2016 and the permanent expulsion of Neil McEvoy from Plaid's Assembly group in 2018.
Despite campaigning to leave in 1975, Plaid campaigned for a Remain vote in the 2016 referendum on the UK's membership of the EU, spending £27,495 on the campaign. In the referendum Wales voted 52.5% in favour of Leave. Immediately after the referendum, Leanne Wood stated that voters 'must be respected' and criticised calls for a second EU referendum. Plaid Cymru later modified their policy to support a People's Vote.
In the Brecon and Radnorshire by-election Plaid Cymru decided not to put up a candidate, but instead to support the Liberal Democrat candidate Jane Dodds in order to maximise the chance of an anti-Brexit candidate winning.
Sixth Senedd (2021–)
In the run-up to the 2021 Senedd election, polling suggested that Welsh Labour would win the highest number of seats but fall short of an overall majority. Pollsters and commentators suggested that the most likely outcome would be another Labour–Plaid Cymru coalition, an option First Minister Mark Drakeford said he would be open to. Price insisted that his party would not be Labour's "junior partner", nor would they work with the Conservatives under any circumstances. He stated that Plaid would be willing to join forces with Labour, but only if the former were the largest party or if it were an equal partnership. Price also said that he did not consider Welsh independence to be "a distraction or a constitutional abstraction", but rather "a practical necessity".
At the election, Plaid increased their seat total to thirteen, up one from the twelve they won in 2016, but lost out in their target constituencies, and lost Rhondda where former leader Leanne Wood lost her seat to Labour. Price said he would not resign, telling ITV Wales: "My job is to lead, its not to give up at a set back or disappointment. My job is to sustain the hope – all those young people who voted for Plaid because they were inspired by our message of the potential we believe is there in Wales to deliver a decent society for our people. I firmly believe that we have sown a lot of seed at this election. A lot of young people in particular who did come with us this time has laid the foundations for the future which I think will set us up for growth in the years to come."
On 22 November 2021, despite Price's earlier comments about refusing to work with Labour, the two parties announced a co-operation agreement consisting of almost 50 different policies, including providing free school meals for all primary school children, the establishment of a free-at-point-of-need national care system and building a railway between North and South Wales. Price called the agreement "a down-payment on independence" and claimed that the results of the Senedd election "confirmed Wales's status as an indy-curious nation. A curiosity that will give birth – sooner than many think – to an independent Wales." He went on to say, "For Wales to be free, we must first be united. And, that is what this Co-operation Agreement sets out to achieve. It launches us on a pathway to a united Wales, one that, sooner than we perhaps think, will find it both comfortable and natural, indeed essential, to join the world community of normal, independent nations."
The co-operation agreement was ratified by Plaid's conference, with 94% voting in favour. "This is a huge step forward for Wales and our democracy," Price said. "The co-operation agreement will bring immediate, tangible and long-term benefit for the people of Wales. All primary school children will now receive free school meals; there will be free childcare for all two-year-olds; and radical action to tackle the housing crisis. There will be stability payments to support family farms; exploration of an accelerated pathway to net zero by 2035; the creation of Ynni Cymru – a company to expand community-owned renewable energy generation; and a new and reformed Senedd – bigger, more diverse, and gender balanced in law. From feeding our children to caring for our elderly, this is a nation-building Programme for Government which will change the lives of thousands of people the length and breadth of our country for the better. And none of it would be happening without Plaid Cymru."
In May 2023, the publication of a report which detailed failings by the party to prevent sexual harassment and bullying led to media coverage suggesting that Price had agreed to resign the party leadership, and Price confirmed this in a statement on 10 May. Acknowledging that he "no longer had the united support of [his] colleagues", Price stated that he would step down officially at the start of the following week, once the process for electing a new interim leader was finalised. On 11 May Plaid Cymru announced that Llyr Gruffydd, Senedd member for North Wales, would replace him as interim party leader, and that this would be confirmed by the NEC on 13 May. On 16 June 2023 Rhun ap Iorwerth was announced as the new permanent leader after he was elected unopposed.
Independence Commission 2020
Before the 2019 general election, Price announced that he would set up a commission to look at the practicality of Welsh independence, and how a Plaid Government would hold an independence referendum. The commission, led by former Dwyfor Meirionydd Plaid MP Elfyn Llwyd, released its report on 25 September 2020. It recommends five key aims for Plaid Cymru:
- Says an independent Wales should seek membership of the European Union, with a possible intermediate step being membership of the European Free Trade Area.
- Recommends that Wales explores a confederal relationship with England and Scotland.
- Proposes improvements to the operation of the Welsh Government and civil service.
- Points the way to drawing up a Welsh Constitution and sets out a framework for a Self-Determination Bill to take the independence process forward.
- A statutory National Commission should provide the people of Wales with a clear understanding of the option for their political future – including through Citizens' Assemblies and an initial referendum to test a range of constitutional options.
It also recommends that there should be one multiple choice referendum to gauge views and to persuade a UK Westminster government to agree to a referendum on the preferred option.

*The 2012 figures exclude Anglesey, where the vote was delayed until 2013. The changes in seats and votes shown for 2012 are a direct comparison since the 2008 elections in the 21 councils up for election (i.e. excluding Anglesey).
In 2008 Plaid won 205 seats including six in Anglesey. For the purposes of this table the 205 figure has been reduced to 199 for the 2012 elections where the party lost 41 of the 199 seats it was defending on the night, leaving them with 158 seats.
In the 2013 elections in Anglesey the party won 12 seats, up from the 6 it won in 2008 (although there were significant boundary changes and a reduction in the total number of seats from 40 to 30).
The 2017 figures are based on changes from the 2012 and 2013 elections. (Hence the slight discrepancy in the percentage increase.)

European Free Alliance
Plaid retains strong links with the Scottish National Party (SNP), with both parties' MPs co-operating closely with one another. They work as a single parliamentary group within Westminster, and were involved in joint campaigning, under the banner of a "Celtic alliance", during the 2001 and 2010 general elections. Both Plaid and the SNP, along with Mebyon Kernow of Cornwall, are members of the European Free Alliance (EFA), a pan-European political party for regionalist, autonomist and pro-independence political parties across Europe. The EFA co-operates with the larger European Green Party to form The Greens–European Free Alliance (Greens/EFA) political group in the European Parliament, although the UK is no longer a member of the European Union.

Mr Michael, who has Prime Minister Tony Blair's backing, has been widely predicted to come first due to the form of electoral system used. An electoral college composed of three groups — politicians, trade unions and party members — will determined the winner. Large unions such as AEEU that have made their choice after a ballot of a small number of delegates are backing Mr Michael, but Mr Morgan has won every union member vote, including the shopworkers' union Usdaw on Tuesday night. Mr Morgan, a left-wing backbencher, has also repeatedly topped opinion polls taken among Labour Party members in Wales.

Mr Wigley's announcement that he was to give up the presidency of Plaid Cymru in May came as a shock. Although he had been in hospital undergoing heart surgery, he was expected to resume his career. Some Assembly members said privately that he had taken on too much — being an MP, AM, party president and also group leader in the National Assembly. But there was also the suggestion that there was a conspiracy to oust him.

But Mr Jones was soon facing questions about his credentials for the job. Seimon Glyn, until then a fairly obscure Plaid Cymru councillor from Gwynedd, had made controversial comments on BBC Radio Wales about inward migration into Welsh-speaking communities. The issue was raised when Mr Jones appeared on the BBC's Question Time in Caernarfon, and he was criticised for his response, in which he at first denied that Mr Glyn had referred to English as a foreign language. There were more problems when Plaid's then chief executive said that Mr Jones was on a learning curve in the job.

According to the document "both parties will then take account of the success of the bedding down of the use of the new legislative powers (which came in after last May's election) already available and, by monitoring the state of public opinion, will need to assess the levels of support for full law-making powers necessary to trigger the referendum".
