Bicester and Woodstock.

On the assisted dying bill, Calum Miller broke from his party four times in a single day -- June 2025 -- voting to tighten eligibility safeguards, including backing two amendments that would have prevented voluntary starvation from qualifying someone as terminally ill. His stance profile confirms the pattern: he sits notably above the Liberal Democrat average on end-of-life safeguards and autonomy measures, suggesting a carefully calibrated position rather than simple opposition to or support for assisted dying. Beyond that, he has voted consistently with Lib Dem positions on scrutinising government power -- backing Lords amendments to the English Devolution Bill, opposing the government's reserve power over pension fund investment, and supporting a referral of the Prime Minister to the Privileges Committee over the Mandelson appointment.

At 72% voting participation, Miller falls below the Commons average, though new MPs with active constituency caseloads sometimes show this pattern. His 97.3% party alignment makes his assisted dying deviations the clearest exception to an otherwise loyalist record. His stance data shows strong alignment with parliamentary and Lords scrutiny (97--100%), climate action (95%), and opposition to employer National Insurance increases (100%), while he scores low on housing development (8%) and progressive taxation (19%) -- both consistent with Lib Dem positioning in the South East.

Outside Westminster, Miller has generated notably positive local coverage, credited with delivering a 4,500-signature petition that shifted East West Rail from closing a level crossing to funding an underpass, and leading a parliamentary campaign that secured £8m for illegal waste cleanup in his constituency. His 276 contributions span defence, the economy, and social care most heavily. He holds no select committee seat, which limits formal scrutiny influence; his impact appears channelled instead through constituency casework and floor speeches.
