Dispatch
3 Jun 2026

A steady but active first-term MP, Alison Bennett has used her platform most visibly on social care -- presenting a "Save the IB" petition at Downing Street, raising carer welfare at Prime Minister's Questions with local evidence, and introducing a Respite and Support Bill to address what she has called carers "reaching breaking point." She has also backed a charity supporting ME/CFS patients and lobbied publicly against the government's proposed local election postponement, appearing on GB News before ministers reversed course.

Her voting participation sits at 72% -- somewhat below the Commons average -- and she has not once broken from the Liberal Democrat line, making her a 100% party-line voter. Her stance profile reflects standard Lib Dem positions: strong opposition to the employer National Insurance rise, backing for Lords scrutiny, and support for parliamentary oversight. She consistently voted against the government on the English Devolution Bill, siding with Lords amendments on local democracy questions, and opposed restoring ministers' reserve powers over pension fund investment. Her voting record places her notably above her party average on pension protection (+19 percentage points) and slightly below on NHS funding and anti-benefit-cut measures.

Her 286 contributions across 221 debates suggest genuine engagement rather than a passive backbench presence, with economy and jobs, social care, and health dominating her speeches -- consistent with her role as the Liberal Democrats' spokesperson on care and carers. No committee memberships are recorded. Local news coverage is high in volume but largely neutral in sentiment, with health and economy stories attracting the most positive scores. She has no rebel votes to date.
