Liz Saville Roberts.

Plaid Cymru's Westminster leader made headlines on assisted dying in June 2025, when she broke from her party's majority position four times during the Report Stage of the Terminally Ill Adults (End of Life) Bill. Most strikingly, she voted against new clauses that her own party backed — including one specifically addressing devolution protections for Wales, Scotland and Northern Ireland. Her voting record places her sharply to the pro-access end of assisted dying debates: she aligns with pro-access positions 88% of the time against her party's 48%, and backs assisted-dying restrictions at 0% against the party's 42%. Beyond that bill, she opposed both the Immigration and Asylum Bill's passage and a reasoned amendment to block it — a consistent nationalist and civil-liberties position rather than a Labour-adjacent one.

At 56% participation across 570 votes, Saville Roberts votes less frequently than the Commons average, though leading a small party group with heavy debating demands partly explains that. She votes against the government agenda 100% of the time across tracked votes, and aligns strongly with workers' rights (98%), climate action (94%) and civil liberties (89%). Her 316 contributions across 209 debates reflect a heavy speech load: economy, social care, crime, defence and health dominate her topics. She has no current committee memberships.

Outside the chamber, she has championed rural utility issues — broadband rollout in Gwynedd and the RTS electricity meter switch-off — and co-founded the local WASPI group in 2017, continuing to press the government on women's state pension injustice. News coverage over the past 90 days is largely neutral in tone across 35 articles. Voting data and speech records are available; committee activity shows none currently listed.
