Stewart's most notable recent act was breaking with Labour on welfare reform. On 9 July 2025, she voted for an amendment that would have extended stronger financial protections to people with fluctuating lifelong conditions — such as Parkinson's, MS, ME and cancer — under the Universal Credit and Personal Independence Payment Bill. Labour's leadership opposed the amendment; Stewart backed it anyway. Outside Westminster, she has built a sustained record on mineworkers' pensions: local press in Ayrshire credited her with lobbying the Chancellor directly, and the Cumnock Chronicle reported that her repeated parliamentary pressure helped secure a Budget commitment on coal staff pension compensation. She has also publicly challenged a government decision to reject pension claims from women, describing it as "indefensible."
At 61% participation — below the Commons average — Stewart votes when present at 99.7% alignment with Labour, making her welfare rebellion the clearest signal of independent judgement. Her voting record shows consistent support for progressive taxation (100% aligned), housing development (93%), and fiscal responsibility (82%). She is markedly less aligned on civil liberties (21%), victims' rights (14%), and Lords scrutiny (7%). Compared with the average Labour MP, she votes more strongly for assisted dying access (+31 percentage points above the party average) and energy security (+24pp), and considerably less often in support of immigration controls (-34pp).
Stewart sits on the Scottish Affairs Committee, which shapes her focus: economy and jobs dominate her speeches (30 contributions), followed by fiscal policy and local government. Her top news coverage ties directly to Ayrshire's post-industrial communities — coal pensions, Royal Mail service points, and social care. News sentiment data for the most recent 90 days is insufficient to assess current local standing.
