One of the most consistent rebels on welfare in this Parliament, Campbell voted against the Universal Credit and Personal Independence Payment Bill at both Second and Third Reading — joining a small group of Labour MPs who refused to back cuts to disability benefits despite heavy government pressure. She also voted for an amendment to protect people with fluctuating conditions such as MS and Parkinson's from losing entitlement, and most recently broke with her party again in January 2026 by voting against regulations expanding police powers over protest near critical infrastructure. Her party alignment sits at 98.9% overall, but on welfare she is a clear outlier — voting with the party position on welfare reform just 25% of the time against a Labour average of 90%.
Her participation rate of 76% is somewhat below the Commons average. She votes consistently with Labour on workers' rights and progressive taxation, and backed the government's Immigration and Asylum Bill and trade union ballot reforms. Her speeches cluster heavily around health and social care — a pattern that helps explain her welfare rebellions — alongside economy, environment, and local government issues. She sits on the Finance Committee and the Petitions Committee.
Locally, Campbell has drawn positive coverage for lobbying the Defence Procurement Minister to locate a new munitions factory in Beith or Ardeer, and her first-year review highlighted over 9,700 constituent emails and 5,500 casework files handled. She has also championed smartphone safety in schools and raised awareness on sepsis. Local news sentiment data for the most recent 90 days is insufficient to assess current coverage trends.
