Brewer's most notable recent act was voting against the Railways Bill at Third Reading in June 2026 — opposing the government's flagship rail nationalisation despite supporting several amendments to it earlier the same day. The Lib Dems broadly backed the bill's direction but raised concerns about concentrating power in the new Great British Railways body and its implications for open-access operators. That vote is the sharpest signal of where Brewer diverges from a straightforward government-friendly stance.
Her parliamentary record is otherwise loyal and active. She votes with the Lib Dems 100% of the time where the party takes a clear position, and her stance profile shows strong alignment with parliamentary scrutiny and Lords oversight — both characteristic Lib Dem priorities. She sits noticeably to the left of her party on benefit cuts and public ownership, while being slightly less pro-business than the Lib Dem average. Her 66% voting participation is below the Commons average, though first-term MPs with active constituency caseloads often show this pattern. Her 77 contributions across 50 debates — covering economy, health, local government, and social care — suggest breadth rather than a single specialism.
Locally, Brewer has generated positive coverage for tangible wins: securing chalk stream protections, lobbying for a long-delayed road repair, and campaigning for North East Hampshire's inclusion in a new strategic authority merging Basingstoke with Farnborough, Fleet, and Aldershot. She is also pushing hard on delays to a new Basingstoke hospital, reportedly at risk of postponement until 2046. She sits on the Women and Equalities Committee. News sentiment over the past 90 days is mixed, with health coverage trending neutral-to-negative — reflecting the hospital dispute rather than criticism of Brewer personally.
