Campbell's most consequential recent actions came in July 2025, when she broke with Labour four times over welfare reform — voting against the Universal Credit and Personal Independence Payment Bill at both Second and Third Reading, backing a reasoned amendment to block it entirely, and supporting a rebel amendment to protect disabled people with fluctuating conditions during the PIP review. She then voted against the government again in January 2026, opposing new regulations expanding Public Order Act powers to criminalise protest near key infrastructure. Five rebel votes in under two years places her among the more independently-minded members of the 2024 intake.
Her voting record otherwise runs at 98.8% party alignment, but the stance data reveals consistent patterns beneath that figure. She sits 55 percentage points above her party average on disability benefits and 25 points above on disability benefit protections — the votes that produced her rebellions. She also scores notably higher than Labour colleagues on civil liberties and public health, and lower on welfare reform. Her 140 parliamentary contributions span health, social care, economy and environment, with health the single biggest category. Participation at 77% sits modestly below the Commons average.
Local coverage has been consistently positive, dominated by constituency casework — her office handled over 5,500 cases in her first year — alongside advocacy for a new munitions factory at Beith or Ardeer and campaigns on smartphone safety and sepsis awareness. She sits on both the Finance and Petitions Committees. Her background in health and social care directly informs her parliamentary focus; her deviations from the Labour whip cluster almost entirely around disability and welfare policy, which is where her personal priorities and party direction have most visibly diverged.
