Simon Hart was the serving government chief whip at the time of his defeat in 2024. Hart represented the former Carmarthen West and South Pembrokeshire seat from 2010 to 2024.

Davies was one of two newly elected Plaid Cymru MPs in 2024.

Political Career

Davies is a member of the House of Commons Welsh affairs select committee (since October 2024). The Welsh affairs committee examines the UK government’s policy and spending as it relates to Wales. Its primary role is to scrutinise the work of the secretary of state for Wales and the Wales Office.

In January 2026, Davies was listed as a supporter of an amendment to the Public Office (Accountability) Bill, often referred to as the “Hillsborough Law”, that would extend the proposed criminal offence of misleading the public to include MPs and peers. Luke Myer, the Labour MP behind the proposal, argued that his amendment would mean “no-one in parliament would be above the law”, adding: “If politicians deliberately lie to the public, there should be consequences.”

Myer stated: “This amendment is a proportionate, carefully safeguarded response to a real democratic risk. It is not about stifling debate or political disagreement, it is about ensuring that those who seek or hold public office cannot deliberately and knowingly mislead the public without consequence.

“The polling shows that voters across the political spectrum expect parliament to act.”

Myer’s amendment won the support of 30 cross-party MPs.

Davies is listed as a member of the all-party parliamentary groups (APPGs) for children in Wales, Fairtrade, hospitality, events, major food and drink businesses in Wales and local markets.

Davies delivered her maiden speech on 5 September 2024 in a debate on the Great British Energy Bill.

In it, she said: “Caerfyrddin is a microcosm of Wales. We have the lush green Tywi, Taf and Teifi valleys, rich in natural beauty, and to the south and east we have a proud industrial heritage with the coalmines of Cwm Gwendraeth and Dyffryn Aman.

“Those communities, like so many across Wales, still bear the scars of that industrial past – poor housing, low-paid work, and poor health outcomes are legacies that we must all address. We are all too aware of the effects that that extractive economy has had on Wales.”

She added: “I was born and raised in Llanarthne. I have moved only four miles in my entire life. I farmed there. I have a tenanted dairy farm unit with my husband Gareth, who is up in the gallery with my family and friends. I am a mother of three daughters and a mamgu of seven…

“The path forward must be one where Wales controls its own destiny, where the wealth of our natural resources enriches our people and where the decisions that shape our future are made not in boardrooms far away but by the very people who live and work in our communities.”

Before entering parliament, Davies was elected as a Plaid Cymru councillor on Carmarthenshire County Council in 2017. She stepped down from this role in 2025.

Political views

Plaid Cymru, officially Plaid Cymru – The Party of Wales, is a social-democratic political party in Wales that advocates for Welsh independence.

Brexit and Europe

Customs union vote (2025): In December 2025, Davies voted in favour of the UK-EU Customs Union (Duty to Negotiate) Bill. The bill, introduced under the 10-minute rule procedure by Liberal Democrat Europe spokesperson Al Pinkerton, sought to mandate the government to enter into negotiations with the European Union to establish a bespoke customs union. In total, 13 Labour MPs joined the Liberal Democrats in supporting the motion, while the majority of the party abstained.

Electoral reform

Proportional representation bill: In December 2024, Davies voted in favour of the Elections (Proportional Representation) Bill – introduced by Liberal Democrat frontbencher Sarah Olney under the 10-minute rule procedure. The bill sought to “introduce a system of proportional representation for parliamentary elections and for local government elections in England”.

A total of 138 MPs supported the bill – with 136 opposed. Notably, 59 Labour MPs backed Olney’s bill.

Introducing the bill, Olney told the House: “First past the post is a broken and unfair system. This summer, the Labour party won a landslide election victory, securing 63% of seats in the House of Commons in return for just 34% of the vote.

“The system leaves millions of voices unheard and creates a divisive, adversarial political climate where collaboration is discouraged and accountability is often sidestepped.”

Welfare

Winter fuel payment EDM: In September 2024, Davies signed an early day motion (EDM) expressing concern over the government’s proposed changes to the winter fuel payment. The motion called on the government to “postpone the ending of winter fuel payments and establish a comprehensive strategy to tackle fuel poverty, health inequality and low incomes among older people.”

Assisted dying

Davies voted against the Terminally Ill Adults (End of Life) Bill, better known as the assisted dying bill, at both second reading (November 2024) and third reading (June 2025).

Social values and conscience issues

Abortion decriminalisation (2025): Davies voted in favour of a backbench amendment to the Crime and Policing Bill that sought to decriminalise abortion in England and Wales in June 2025. The amendment, which was passed by a majority of 242 votes, removed women from the threat of prosecution for ending a pregnancy at any stage. As an issue of conscience, MPs were allowed to vote according to their personal beliefs.

Palestine

Palestinian recognition letter (July 2025): In July 2025, Davies was among the over 254 MPs to sign a cross-party letter calling for the government to immediately recognise the state of Palestine. The letter called on the prime minister and foreign secretary to recognise Palestine at the UN Conference then taking place in New York.
