Green Party of England and Wales MP for Brighton Pavilion.
One moment of genuine independence stands out in Berry's recent record: in December 2025 she broke with the Green Party to vote for capping inheritance tax relief on farms and family businesses — a significant rebel vote that put her at odds with rural landowner interests and signalled a harder fiscal line than her party took. More recently, she has been one of the louder opposition voices calling on Keir Starmer to resign over the Peter Mandelson vetting affair, and she has used her platform to press ministers on local transport access for disabled constituents at Brighton station.
Berry votes with the Greens on almost everything — a 99.8% alignment rate — and her stance profile confirms a consistent pattern: strongly pro-workers' rights (96%), pro-climate action (96%), and pro-welfare expansion (95%), with near-total opposition to pro-business and anti-tax positions. Her participation rate of 79% sits a little below the Commons average. She deviates from her party's average on small business protection and whistleblower protection, voting more strongly for both than most Green MPs. She has made 385 contributions across 147 debates, with economy, crime, local government, and social care dominating her speeches.
Berry sits on no select committees, which limits her formal scrutiny role, though her news coverage suggests active constituency casework — transport access, anti-fascist community protection, and housing safety following Grenfell all feature prominently. Local news coverage over the past 90 days has been high-volume but largely neutral in tone, with stronger positive scores reserved for stories about her parliamentary performance. Voting data goes back to July 2024 when she first entered the Commons.
Siân Berry is the Green Party MP for Brighton Pavilion, and has been an MP continually since 4 July 2024. She currently undertakes the roles of Green Spokesperson (Crime and Policing), Green Spokesperson (Justice), Green Spokesperson (Transport), Green Spokesperson (Work and Pensions), Green Spokesperson (Culture, Media and Sport), and Green Spokesperson (Democratic Standards).
