Marie Tidball.

One act sets Tidball apart from nearly all her Labour colleagues: on 1 July 2025, she voted against the government's Universal Credit and Personal Independence Payment Bill at Second Reading — one of a small number of Labour MPs to rebel on welfare reform legislation that would tighten disability benefit assessments and restrict access to the health component of Universal Credit. For an MP who was herself identified as one of three newly elected disabled MPs in 2024, the vote carries particular weight. It is the only departure from the Labour line in her voting record.

Otherwise, Tidball is a 99.8% party-line voter with a 79% participation rate — slightly below the Commons average — and no committee roles. Her speeches concentrate heavily on social care, health, and the economy, with local government also featuring prominently; she votes well above her party average on local-government-powers measures. She is fully aligned with progressive taxation positions and strongly backs public ownership votes, including railway nationalisation in June 2026. She votes notably less often than her Labour peers in favour of NHS funding and pension protection measures, though the reasons for those gaps are unclear from voting data alone.

Tidball won Penistone and Stocksbridge in July 2024, overturning a substantial Conservative majority held by Miriam Cates, who had faced a parliamentary standards investigation before losing her seat. Local news coverage over the past 90 days — across 70 articles — is broadly neutral, with transport and the economy the dominant issues. No negative coverage of Tidball's own conduct appears in the data. Her disability-advocacy background, noted at the time of her election, appears to inform her welfare reform rebellion, though she has not held a committee seat to date.
