Stone broke ranks with his Liberal Democrat colleagues five times on 20 June 2025, all on the Terminally Ill Adults (End of Life) Bill -- voting to tighten eligibility rules around voluntary stopping of eating and drinking, and to strengthen procedural safeguards in the assessment process. These were not minor procedural rebellions: they placed him noticeably to the right of his party on end-of-life autonomy, where his voting record runs 28 percentage points above the Lib Dem average. Beyond the chamber, he has been active in the press -- lobbying the Prime Minister on Scotch whisky tariffs in China, challenging NHS Highland over a constituent trapped in hospital for 450 days, and confronting a UK Government minister over the loss of banking services in rural communities. None of these battles have yet produced clear wins.

At 64% participation, Stone votes somewhat below the Commons average. He is a 97% party-line voter overall, consistently opposing the Labour government on Lords amendments and fiscal measures. His stance profile shows strong support for Lords and parliamentary scrutiny (100% aligned on both), backing for business and climate action, and firm opposition to the employer National Insurance increase. He speaks most on economy and jobs, local government, and fiscal policy -- a pattern that tracks the particular pressures on a remote Scottish constituency.

Chairing the Petitions Committee gives Stone a platform beyond his own brief, and his local news coverage consistently shows him intervening on rural service provision -- banking, healthcare, transport -- rather than abstract policy debates. His nuclear energy advocacy and criticism of the Scottish Government as "short-sightedly stubborn" on the issue suggest a willingness to cut across devolved political lines when he sees an economic case for his area. Voting data and news coverage are available from 2025 onwards.
