A marginal seat — won by just 637 votes (2.0%) in 2024. Covers Holyhead, Llangefni and Menai Bridge. Population 68,890, notably older (median age 48 vs 41 nationally). Recorded crime is 52% below the national average. Median income £25K (below average).

Llinos Medi's most visible work has been a sustained campaign to revive the Wylfa nuclear power station on Ynys Môn. She has raised the project repeatedly in Parliament, tabled amendments, organised cross-party roundtables and called it "a no-brainer" for the island's economy. That single issue dominates her 120 parliamentary contributions -- she has spoken across 88 debates, with economy and jobs accounting for more than half her speeches, followed by energy and environment. She has also challenged the government on rural exclusion from flagship economic schemes and joined Plaid Cymru's campaign over women's state pension injustice, describing the treatment of affected women as a "profound moral failure."

Her participation rate of 57% sits below the Commons average, though that figure is not unusual for Welsh and nationalist MPs who balance Westminster with strong local commitments. She votes 100% with Plaid Cymru and has no rebel votes on record. Her stance profile shows strong alignment with workers' rights (91%) and climate action (86%), but consistent opposition to fiscal tightening -- she voted against the employer National Insurance increase on every occasion -- and scores just 19% on fiscal responsibility measures. She sits on the Welsh Affairs Committee, giving her a formal platform on cross-border policy.
