Edinburgh South West.

All five of Scott Arthur's rebel votes came on a single day -- 20 June 2025 -- and all concerned assisted dying. He voted against the Terminally Ill Adults (End of Life) Bill at its Third Reading, having also opposed an amendment that would have tightened eligibility criteria around voluntary starvation. His deviation from Labour's majority makes him noticeably more sceptical of the Bill's passage than most of his colleagues, though his stance profile shows him running 15 percentage points above the party average on assisted-dying access -- suggesting his objections may have been procedural or about specific provisions rather than blanket opposition. Beyond Parliament, Arthur secured arguably his most tangible legislative achievement when his Rare Cancers Bill became law in early 2026, a private member's bill driven in part by his father-in-law's death from a brain tumour and developed with more than 40 charities.

At 83% voting participation -- broadly in line with the Commons average -- and 97.7% party alignment, Arthur is otherwise a dependable government loyalist. His speeches, spread across 385 contributions in 221 debates, skew heavily toward the economy, defence, health, and social care. On workers' rights he votes with Labour nearly nine times in ten; on fiscal responsibility around three in four. He sits notably low on parliamentary scrutiny (27%) and is firmly against Lords influence (0% on Lords scrutiny alignment), consistent with a backbencher who largely backs the executive.

Arthur's membership of the Transport Committee helps explain his local interventions -- he has pressed delivery companies over dangerous riders in Edinburgh and secured retail pledges on firework sales. His medical background (he is a doctor) tracks directly to his health policy focus and the rare cancers legislation. News coverage over the past 90 days is thin but leans positive, with health stories scoring highest. Constituency-level data is limited beyond press reporting.
