Calum Miller.

Calum Miller's most notable recent act was breaking with his party on assisted dying. On 20 June 2025, he voted against the Terminally Ill Adults (End of Life) Bill at Third Reading — one of only a handful of Liberal Democrat MPs to do so — and backed two amendments that would have disqualified applicants whose wish to die was substantially driven by fear of being a burden, financial hardship, or lack of access to care. Both amendments were defeated. His stance sits well outside his party's centre of gravity: on assisted dying access, he votes in line with party colleagues just 13% of the time, against a Liberal Democrat average of 72%. Outside the chamber, he has won positive local coverage for constituent campaigns — delivering a 4,500-signature petition over a level crossing dispute that ended with an underpass solution, and pressuring the government and Environment Agency to commit £8m to clearing an illegal waste site in his constituency.

His voting participation stands at 71% — somewhat below the Commons average — and he votes with the Liberal Democrat majority 97.5% of the time outside the issues where he deviates sharply. His stance profile shows strong alignment with parliamentary and Lords scrutiny, climate action, and business-friendly positions, but low alignment with fiscal-responsibility and progressive-taxation measures. He has opposed planning delegation regulations that would remove elected councillors from smaller planning decisions — consistent with a pro-local-democracy position that scores 62% across his votes. His 316 contributions across 239 debates are spread heavily across defence and economy topics.

Miller has no current select committee role. His civil service and academic background appears to inform a focus on policy detail. News sentiment over the past 90 days is broadly neutral, with environment and transport coverage dominating. The assisted dying votes are the clearest signal of independent judgment in an otherwise loyalist record.
