Ayr, Carrick and Cumnock.

Stewart's most significant break with Labour came in July 2025, when she voted for an amendment that would have protected disabled people with fluctuating conditions during the government's ongoing PIP assessment review -- one of a small number of Labour MPs to back that protection against her own party's position. Beyond that rebel vote, her most prominent work has been a sustained campaign on behalf of former coalfield workers: multiple local news outlets credit her with lobbying the Chancellor directly and helping secure a Budget commitment on mineworkers' pensions, a 30-year fight for communities in Ayr, Carrick and Cumnock.

At 59% voting participation, Stewart sits meaningfully below the Commons average. Where she does vote, she follows Labour's line 99.7% of the time -- making the disability benefits deviation stand out. Her stance profile shows notable distance from her party on pension protection (she votes for it far less often than Labour colleagues), criminal justice reform, and armed forces welfare, while sitting above the party average on public health and disability benefits votes. Her 59 contributions span economy, fiscal policy, local government, health and social care -- a spread that reflects both the post-industrial character of her constituency and a generalist rather than specialist approach.

Stewart sits on the Scottish Affairs Committee, which gives her a formal role scrutinising devolved and reserved matters affecting Scotland. Her news coverage -- particularly in the Cumnock Chronicle and Daily Record -- is heavily positive on constituency casework, though recent 90-day sentiment is more mixed, with constitution and democracy coverage scoring near zero. Data on her committee contributions is not available here, and her speech record runs only to March 2026.
