A new constituency created in the 2023 boundary review. Won by Lab in its first election in 2024. Covers Mirfield, Liversedge and Gomersal and Birkenshaw. Population 97,819.

The defining fact about Kim Leadbeater right now is her sponsorship of the Terminally Ill Adults (End of Life) Bill -- the most significant piece of private member's legislation in years. She has attracted sharp criticism for the way she managed the bill's committee stage, with opponents accusing her of stacking the scrutiny committee with supportive MPs to limit challenge. A March 2026 article scoring among the most negative coverage in her recent press described the move as a "ruthless manoeuvre designed to evade scrutiny." Her voting record on assisted dying deviates from her party in a distinctive direction: she sits 14 points below the Labour average on assisted dying safeguards and 9 points above it on anti-assisted-dying alignment -- an unusual profile for the bill's own sponsor, suggesting she has resisted some amendments intended to strengthen oversight.

Beyond the assisted dying controversy, Leadbeater is a high-participation MP -- 92% of votes cast -- and votes with Labour 100% of the time, including consistently backing the government's position in recent Lords ping-pong on both the Children's Wellbeing and Schools Bill and the Pension Schemes Bill. Her stance profile shows strong alignment with workers' rights (90%) and progressive taxation (97%), while sitting at just 5% on parliamentary scrutiny -- consistent with backing the government over Lords and amendment challenges. Her 525 parliamentary contributions skew heavily toward health and social care.
