Plaid Cymru MP Liz Saville Roberts holds the seat on 53.9% of the vote — a split-council geography across 2 councils.
1 Jun 2026
Liz Saville Roberts' most striking recent move was breaking with Plaid Cymru four times on the Terminally Ill Adults (End of Life) Bill -- voting against her party's majority on amendments covering advertising restrictions, employer opt-outs, and key new clauses at Report Stage in May and June 2025. Her votes consistently pushed against the bill's direction, and she sits notably below her party's average on assisted-dying safeguards (0% versus the party's 25%), suggesting a principled opposition to the legislation rather than isolated dissent. Beyond Westminster, she has drawn local coverage for championing broadband upgrades in Gwynedd, lobbying for Welsh pubs to access Scottish-style guest beer rules, and condemning the government's handling of WASPI women's pension compensation -- which she called a "profound moral failure."
She votes in roughly half of all parliamentary divisions, a participation rate below the Commons average, though she contributes actively in debate -- 295 contributions across 192 debates, with economy, social care, health, crime, and defence dominating her speech topics. She is a near-total party-line voter (98.6%) outside the assisted dying votes, and her stance profile marks her as strongly pro-workers' rights (91%) and strongly opposed to immigration control measures (9% aligned), consistent with her recent votes against asylum support regulations. She also backs Lords scrutiny at a 77% rate and leans pro-civil-liberties.
Saville Roberts holds no current committee seats, which limits one formal avenue for detailed legislative influence. Her deviation data flags one curiosity: she votes more strongly in favour of armed forces welfare than her Plaid Cymru colleagues (+33 percentage points above the party average). News coverage over the past 90 days spans 151 articles but averages close to neutral in sentiment, spread across crime, culture, and environment topics, with no single dominant story.
