Rachael Maskell is the Labour and Co-operative MP for York Central, first elected in 2015 and reelected in 2024 with 24,537 votes (56.6 percent) and a majority of 19,154. In July 2025 she led the largest welfare rebellion against the Starmer government, was one of four Labour MPs who had the whip withdrawn, and sat as an independent for four months before it was restored in November 2025. She was the key organiser, not a passing dissenter. She called the welfare bill "an omnishambles" and the cuts "Dickensian cuts that belong to a different era and a different party." More than 120 Labour MPs joined the campaign at various stages, with 47 ultimately voting against the government, and the rebellion forced ministers to drop the most significant disability benefit cuts, a concrete policy outcome traceable to her leadership.

Born July 1972 and a physiotherapy graduate of the University of East Anglia, she spent 20 years in the NHS, first as a care worker and then as a senior physiotherapist in intensive care and acute medicine, work in ITU where she saw patients die, before becoming Head of Health at Unite, the UK's largest trade union. That combination of clinical frontline experience and trade union leadership gives her a dual authority on health that few MPs possess.

She is Vice Chair of the Health and Social Care Select Committee. She has advanced legislation to regulate short term holiday lets, directly relevant to York where Airbnb style rentals have displaced long term housing, and introduced a Bill to tackle bullying at work, specific legislative contributions to her name. Her shadow career included Shadow Minister for Rail and Transport, Shadow Secretary of State for Environment, Food and Rural Affairs (2016-2017, resigned over Article 50), and further frontbench roles until she resigned in 2021 over compulsory Covid vaccination for NHS staff. "There are lines I can't cross because of where I come from in politics with my faith," she told the chief whip during the 2025 welfare crisis.

After the whip was restored she said: "I should never have been suspended in the first place. All I did was speak up for disabled people and especially people in poverty." She told the BBC: "I don't see myself as a rebel."

The Green Party took 5,185 votes (11.9 percent) in York Central in 2024. During her suspension some constituents called for her resignation, arguing her independent status undermined her mandate. She remained and was reinstated.

Maskell's strengths include 20 years of NHS clinical experience including ITU, Unite Head of Health providing trade union leadership, Vice Chair of the Health Select Committee, the welfare rebellion leadership forcing concrete government concessions, the short term holiday lets legislation, the bullying at work bill, a 19,154 majority, and the demonstrated willingness to accept the whip being withdrawn over principle. Her weaknesses include four separate frontbench resignations or removals (Article 50, compulsory vaccination, and the 2025 welfare suspension), no ministerial office despite a decade in Parliament, constituency backlash during the suspension, and the growing Green vote in York. At 53, with a safe seat and the vice chair of the health committee, she has both platform and record. The welfare rebellion produced an actual policy change. That is more than most backbenchers achieve in a career.
