Sioned Williams

Sioned Williams is a Welsh politician and a Member of the Senedd (MS) for the South Wales West region since 2021.

Williams is a member of Plaid Cymru.

Williams was born in Monmouthshire and was educated at Ysgol Gymraeg Cwmbrân and Ysgol Gyfun Cwm Rhymni.

She attended Aberystwyth University where she studied Welsh and English.

Later, she attended Cardiff University with a S4C T. Glynne Davies Scholarship.

She was a journalist for BBC News Wales, and later worked at Academi Hywel Teifi in Swansea University, organising public events and community courses on Welsh history, culture and literature.

Williams' great uncle Dai Wil, was an agent for Aneurin Bevan in one of his early elections.

The majority of Williams' family were Labour Party supporters, other than her mother, who voted Plaid Cymru "to remind them that we're here".

Sioned said that the miners' strike, the Campaign for Nuclear Disarmament and the campaign to establish S4C were all "certainly formative features of my youth".

A self-proclaimed democratic socialist, she became a member of Plaid because "[she] felt that the Labour lordship of the Gwent Valleys where [she] grew up had become a damaging hegemony, which had lost contact with the culture and people it once represented and defended."

Furthermore, Williams believes "the current UK political system does not offer the people of Wales an equitable and prosperous future."

In the 2017 local elections, Williams contested the Alltwen ward on Neath Port Talbot council.

Sioned is the Plaid Cymru spokesperson for post-16 education, Social Justice and Equalities, having held these portfolios since her election.

She is also a member of the Senedd's cross party committees for Children, Young People and Education; and Equality and Social Justice.

As of 2021, Sioned was a Community Councillor for Alltwen and Chair of Cilybebyll Community Council.

She previously served as Chair of Governors of Ysgol Gynradd Gymraeg Pontardawe for five years, and then became governor of Ysgol Gymraeg Ystalyfera Bro Dur.

She has also worked for Plaid Cymru as head of strategic communications.

Sioned has campaigned passionately on many matters of social justice and inequality since her election.

Notably, she successfully helped to secure a reopening of the enquiry into the Gleision Colliery mining accident in Cilybebyll after campaigning alongside the victims’ families for several years.

Sioned's husband, Daniel Gwydion Williams, is a professor of English Literature at Swansea University; he is also a writer and a semi-professional jazz musician.

The couple live in Alltwen, Swansea Valley with their two teenage children.
