North West Hampshire.

Malthouse's most prominent recent votes have been on assisted dying, where he broke from the Conservative majority five times on 20 June 2025 during the Terminally Ill Adults (End of Life) Bill's Report Stage. He voted against procedural moves his party supported, and split from the Conservative majority on the contested question of whether voluntary stopping of eating and drinking should qualify someone as terminally ill -- voting in two directions across related amendments, suggesting a cautious rather than ideologically fixed approach to the bill's scope. He has otherwise voted in line with standard Conservative opposition positions: backing the referral of Keir Starmer to the Privileges Committee over the Mandelson appointment, opposing the government's pension investment powers, and siding with Lords amendments on the English Devolution and Community Empowerment Bill.

At 74% participation, Malthouse votes somewhat below the Commons average. He is a 96% party-line voter on most issues, with his strongest deviations being a markedly higher civil liberties alignment than his Conservative peers, and notably lower support for pension protections and criminal justice reform. His 394 contributions across 141 debates place him among the more active speakers; social care, health, and the economy dominate his speech record.

Outside Parliament, his local press coverage is active and largely practical -- heating oil price spikes, A34 road safety, Remembrance parade costs, and housing planning powers have all drawn his public intervention. He sits on the Science, Innovation and Technology Committee. His former roles as a minister (including Chancellor of the Duchy of Lancaster) and his time as Deputy Mayor of London under Boris Johnson provide background context, though they do not visibly drive his current parliamentary focus.
