ⓘ Plaid Cymru


ⓘ Plaid Cymru

Plaid Cymru is a social-democratic political party in Wales advocating Welsh independence from the United Kingdom within the European Union.

Plaid was formed in 1925 and won its first seat in the UK Parliament in 1966. The party holds four of 40 Welsh seats in the UK Parliament, 10 of 60 seats in the National Assembly for Wales, and 202 of 1.264 principal local authority councillors. It is a member of the European Free Alliance.


1. Platform

Plaid Cymrus goals as set out in its constitution are:

  • To create a bilingual society by promoting use of the Welsh language;
  • To promote Wales contribution to the global community and to attain membership of the United Nations.
  • To build a national community based on equal citizenship, respect for different traditions and cultures and the equal worth of all individuals, whatever their race, nationality, gender, colour, creed, sexuality, age, ability or social background;
  • To ensure economic prosperity, social justice and the health of the natural environment, based on decentralist socialism;
  • To promote the constitutional advancement of Wales with a view to attaining independence within the European Union;

In September 2008, a senior Plaid assembly member spelled out her partys continuing support for an independent Wales. The Welsh Minister for Rural Affairs, Elin Jones, began Plaids annual conference by pledging to uphold the goal of making Wales a European Union member state. She told the delegates in Aberystwyth that the party would continue its commitment to independence under the coalition with the Welsh Labour Party.


2.1. History Beginnings

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 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 partys first president, offered himself in Caernarvonshire on a platform of demonstrating Welsh peoples rejection of English dominion.


2.2. History 1930s

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 partys 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 partys leading members including President Saunders Lewis towards Europes 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 judges dismissal of the use of Welsh and their subsequent imprisonment in Wormwood Scrubs, led to "The Three" becoming a cause celebre. This heightened the profile of the party dramatically and its membership had doubled to nearly 2.000 by 1939.


2.3. History 1940s

Penyberth, and Plaid Cymrus 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.


2.4. History 1950s

Gwynfor Evanss 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 Cymrus 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.


2.5. History 1960s

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.

Labours 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 governments 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 Labours policies as a threat to the viability of small Welsh communities.


2.6. History 1970s

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 campaigned to leave The Common Market in the 1975 referendum. Wales and The UK voted to remain.

Plaid Cymrus 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 Cymrus ambivalence toward home rule as opposed to outright independence the referendum result led many in the party to question its direction.

At the 1979 general election the partys 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.


2.7. History 1980s

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 Mon from the Conservatives in 1987. In 1989 Dafydd Wigley once again assumed the presidency of the party.


2.8. History 1990s

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 partys 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 Labours 28. In doing so, it appeared to have broken out of its rural Welsh-speaking heartland, and captured traditionally strong Labour areas in industrial South Wales.


2.9. History 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, 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 Partys 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 Joness former seat of Ynys Mon to Albert Owen, although it gained Carmarthen East and Dinefwr, where Adam Price was elected.


2.10. History Second National Assembly, 2003–07

The Assembly elections of May 2003 saw the partys representation drop from 17 to 12, with the seats gained in the 1999 election falling again to Labour and the partys 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 Cymrus 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 Iwans 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 partys 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 Mon. Overall therefore, Plaid Cymrus Parliamentary representation fell to three seats, the lowest number for the party since 1992. The partys share of the vote fell to 12.6%.

In 2006, the party voted constitutional changes to formally designate the partys 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 also saw the party unveil a radical change of image, opting to use "Plaid" as the partys name, although "Plaid Cymru - the Party of Wales" would remain the official title. The party changed its logo in 2006, from the traditional green and red triban three peaks used since 1933, to a yellow Welsh poppy Meconopsis cambrica.


2.11. History 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 Cymrus Mohammad Asghar become the first ethnic minority candidate elected to the Welsh Assembly. The partys 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 Governments 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.

In the 2010 general election, Plaid returned three MPs to Westminster. They took part in the Yes for Wales cross-party campaign for the March 2011 referendum.


2.12. History Fourth National Assembly, 2011–16

In the 2011 National Assembly election Plaid slipped from second place to third, being overtaken by the Welsh Conservative Party 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 partys 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 be abandoning her relatively safe list seat to stand in a constituency at the 2016 National Assembly elections; she later confirmed she would contest the Rhondda. Adam Price was subsequently selected as the partys candidate for Carmarthen East and Dinefwr. Lindsay Whittle confirmed he would contest the Caerffili constituency.

On 20 June 2013, former party leader Ieuan Wyn Jones stood down from the Assembly as the member for Ynys Mon. Plaid Cymrus 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.


2.13. History Fifth National Assembly, 2016–present

Following the 2016 Welsh Assembly elections, having gained one seat, Plaid Cymru became the Assemblys second-largest party and briefly became the official opposition to the Welsh Government with 12 seats. As of February 2018 Plaid Cymru had ten Assembly Members, following the resignation of Dafydd Elis-Thomas in 2016 and the permanent expulsion from Plaids Assembly group of Neil McEvoy in 2018.

Despite campaigning to leave in 1975, Plaid campaigned for a remain vote in the 2016 referendum on the UKs membership of the EU. Wales voted 52.5% in favour of leave.

Immediately following the referendum, Leanne Wood publicly stated that voters must be respected and criticised calls for a second EU referendum. Plaid Cymru later modified their policy to support a Peoples Vote.

In the 2017 United Kingdom general election Plaid saw their popular vote fall, but narrowley gained Ceredigion and saw Arfon become highly marginal.

In September 2018, Adam Price won the partys leadership election, defeating the incumbent Leanne Wood and fellow challenger Rhun ap Iorwerth.

In the Brecon and Radnorshire by-election Plaid Cymru decided not to put up a candidate, and instead to support the Liberal Democrat candidate Jane Dodds in order to maximise the chance of an anti-Brexit candidate winning.

In the 2019 United Kingdom general election Plaid stood aside in four seats to endorse Unite to Remain candidates, at the election Plaid held their four seats and saw a slight decrease in their popular vote.


2.14. History Undeb Credyd Plaid Cymru

4. Electoral performance

Local elections

*The 2012 figures excludes 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 significant boundary changes took place along with a reduction in the total number of seats available 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

UK general elections

*Six seats contested on a joint Plaid Cymru/Green Party ticket


5. European Free Alliance

Plaid retains close 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 during the 2005 general election campaign. 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 not a member of the European Union.
