Swindon South.
Labour Party MP Heidi Alexander holds the seat on 48.4% of the vote.
1 Jun 2026
Heidi Alexander is Secretary of State for Transport -- a Cabinet role that makes her one of the more powerful MPs in the House, and the dominant fact shaping her parliamentary record. In that capacity she secured £20 million for a Swindon estate described as "uncared for and unloved," launched a £165 million transport fund targeting housing development, and has been publicly championing bus and rail improvements directly relevant to her constituency. Her speeches, 648 contributions across 68 debates, are heavily weighted toward transport and the economy, reflecting her ministerial brief rather than backbench campaigning.
Her voting record is exactly what you would expect from a Cabinet minister: 100% party alignment, no rebel votes, and participation at 61% -- below the Commons average, but typical for ministers whose time is consumed by departmental work rather than chamber attendance. She votes consistently for workers' rights and progressive taxation, and has backed government moves to tighten asylum support rules and override repeated Lords amendments to the Pension Schemes Bill. Her stance scores show notable distance from her party on criminal justice reform (20% versus the Labour average of 64%) and climate action (41% versus 52%), though voting absences rather than rebel votes likely explain much of that gap.
The broader picture is of an MP whose influence runs through Cabinet rather than Parliament. Local news coverage -- dominated by transport (56 articles) and housing -- is broadly positive, with her ministerial role frequently credited for funding wins in Swindon South. She sits on no select committees, which is standard for Cabinet ministers. Speech data runs to March 2026; voting data covers April 2026.
