Rimmer's most significant recent actions have been her rebel votes against the government's disability benefit cuts. In July 2025 she voted against clauses reducing the Universal Credit health top-up for new claimants and backed an amendment to extend protections to people with fluctuating conditions such as Parkinson's and MS. She also broke ranks in February 2026 to back two amendments that would have banned UK Export Finance from supporting supply chains linked to modern slavery — both defeated by the Labour majority. Most recently, she voted against a planning regulations instrument in July 2026, again against her party. At 93.2% party alignment overall, she is no rebel by habit, but on welfare and anti-slavery provisions she has been willing to defy the whip.
Her participation rate of 65% sits below the Commons average. She votes consistently for workers' rights (90% aligned) and progressive taxation (100% aligned), while her voting record places her sharply at odds with her party on welfare: she deviates 65 percentage points below Labour's average on welfare reform and 59 points above on welfare protection. She has also voted more restrictively than most Labour MPs on assisted dying. Her 32 speeches across 25 debates cover defence, social care, economy and jobs, and health — and she drew local attention in February 2026 by warning in a select committee debate that some St Helens residents have a healthy life expectancy of just 57.
Rimmer has no current committee roles, which limits her formal scrutiny function. Recent local news coverage over the past 90 days is broadly neutral in tone, spanning crime and culture topics. Her specialist focus on health inequality and her constituency's economic pressures — she welcomed a new industrial furnace project in St Helens in June 2025 as a jobs opportunity — provides context for her welfare voting pattern. No committee data is available to supplement the picture further.
