Ruth Jones was elected Labour MP for Newport West in an April 2019 byelection following the death of Paul Flynn, whom she describes as her "friend and political mentor." She held the seat at the 2019 general election with a reduced majority of 902, and in 2024, on the new Newport West and Islwyn boundaries, won 17,409 votes (41.5 per cent) and a majority of 8,868, with Reform UK second on 20.4 per cent and the Conservatives collapsing to 16.0 per cent. She had previously stood twice in Monmouth, in 2015 and 2017, finishing second both times before her selection for winnable Newport West.
Born on the Gaer estate in Newport in April 1962 and a physiotherapy graduate of Cardiff University, she worked as an NHS physiotherapist for over 30 years at Nevill Hall Hospital, the Panteg Stroke Unit and the Serennu Children's Centre, and rose to be President of the Wales Trades Union Congress, the most senior trade union position in Wales.
In Parliament she served as Shadow Minister for Flooding and Coastal Communities (2020) and then Shadow Minister for Environment, Food and Rural Affairs (2020 to 2024). She was elected Chair of the Welsh Affairs Committee on 9 September 2024 and sits on the Liaison Committee, and chairs the APPG for Safeguarding in Faith Communities while serving as Vice Chair on International Freedom of Religion or Belief. As Welsh Affairs chair she has launched an inquiry into prisons, probation and rehabilitation, citing Nye Bevan and Neil Kinnock as inspirations and describing the committee's cross party work "to get the best outcomes for Wales."
In June 2025 she signed a reasoned amendment backed by over 100 Labour MPs to block the welfare bill, calling the rebellion a "warning shot" to Starmer, and on 11 May 2026 she called on Keir Starmer to resign. A Welsh Affairs Committee chair publicly demanding the Prime Minister's removal is a significant intervention. She introduced a Private Member's Bill on fur imports and sales and a Paternity Leave (Bereavement) Bill, and has campaigned on animal welfare, invisible disabilities and anti vaping in schools.
