Chipping Barnet.

Appointed Exchequer Secretary to the Treasury in September 2025, Dan Tomlinson has been the most consistent rebel in his parliamentary cohort on a single issue: assisted dying. He voted against the Terminally Ill Adults (End of Life) Bill at Second Reading in November 2024, backed strengthening amendments at Report Stage in June 2025, and then voted against the Bill again at Third Reading -- one of a minority of Labour MPs who opposed the legislation at every major Commons hurdle. His five rebel votes against the Labour majority are all on this one issue, making his position distinctive and consistent rather than broadly insurgent.

Tomlinson votes with Labour 98.4% of the time on everything else, and his 641 contributions across 81 debates since 2024 reflect his Treasury brief -- fiscal policy and economy and jobs dominate his speech topics. His participation rate of 61% is below the Commons average, though junior ministers typically miss more votes due to departmental duties. He sits on the Public Accounts Committee, which scrutinises government spending, and his stance data shows he is notably more supportive of welfare reform and armed forces welfare than the average Labour MP, and notably less aligned with civil liberties positions.

His local profile in Chipping Barnet is active: news coverage highlights the launch of a community action network, high street interventions, and local crime and transport casework. An October 2024 interview noted his personal experience of housing insecurity -- context that helps explain why housing featured heavily in his early parliamentary focus before his Treasury appointment shifted his attention. Recent local coverage spans cost-of-living and crime, the two issues generating the most press about his constituency over the past 90 days. Voting data runs to April 2026.
