Political Career

Medi is a member of the House of Commons Welsh affairs select committee (since October 2024) – the committee that 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.

Medi is listed as a member of the all-party parliamentary groups (APPGs) for hospitality, events, major food and drink businesses in Wales (chair), project delivery and the West Coast Main Line.

Medi delivered her maiden speech on 30 July 2024 during a debate on the Budget Responsibility Bill.

In it, she said: “My journey into politics was not typical. As a farmer’s daughter, I grew up understanding the value of hard work, watching my father, a first-generation farmer, establish a farm alongside my mother. I left school at 16 and undertook a care course.

“By the age of 18, I was working as a carer in our care homes. I have been a carer, a teaching assistant and a youth worker. I have also had several other roles, including selling eggs and milk recording on milk farms. In 2013, I entered politics, standing as a county councillor.”

She added: “My personal journey has not been typical, either. In 2015, I found myself homeless with my two children. It was tough, but now I am the MP for Ynys Môn.

“As for the most important lesson from my experience, I want to inspire other women to believe that ‘If she can do it, I can do it.’ I aim to bring women along on this journey, regardless of their starting point. I will always be filled with pride when women come up to me to say, ‘Thank you. I’ve gone for it because of you.’

“I am not here for myself. I want people in Ynys Môn who might also have been through a tough time to see my work here and be inspired to put themselves forward.”

Before entering parliament, Medi served as a Plaid Cymru councillor on the Isle of Anglesey County Council from 2013 to 2024. She led the council from 2017 to 2024, becoming the first woman to do so. She was leader of the opposition on the council from 2015 to 2017.

Political Views

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

Plaid Cymru’s constitution states its principal aim is to “secure independence for Wales in Europe.”

The party constitution also defines the party’s objectives around “decentralist socialism”, respect for different traditions and cultures, and creating “a bilingual society by promoting the revival of the Welsh language.”

Brexit and Europe

Customs union vote (2025): In December 2025, Medi 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, Medi 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, Medi 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

Medi voted in favour of 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): Medi 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.

Lying amendment: In January 2026, Medi 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.
