Carla Denyer.

One of Westminster's most active Green MPs, Carla Denyer has used her platform to push well beyond the party's traditional environmental brief. Her most prominent recent interventions have ranged from leading a cross-party call to close animal testing facility MBR Acres, to signing a letter urging a government apology for the Balfour Declaration, to publicly linking the threat of conflict with Iran to Britain's fossil fuel dependency. She also stepped down as Green Party co-leader after the 2024 election to concentrate on her parliamentary role — and the volume of activity since then suggests she has done exactly that.

Her voting participation, at 74%, sits below the Commons average. On policy, she votes with high consistency for workers' rights (94%) and climate action (97%), and against pro-business positions (8% alignment) and housing development measures (27%). That planning scepticism showed up concretely in July 2026, when she voted against regulations requiring smaller planning applications to be decided by officers rather than elected councillors, prioritising local democratic scrutiny over development speed. Her one rebel vote came on the assisted dying bill, where she voted against a requirement to assess palliative care provision in early annual reports — the sole departure from Green Party positions on record.

Denyer sits on the Environmental Audit Committee, which aligns with her most frequent speech topics: economy and jobs, environment, energy, and housing, together accounting for well over half her 213 contributions across 105 debates. She departs from her party's average notably on fiscal consolidation, voting for it more often than fellow Greens (67% vs 47%). News sentiment data for the most recent 90 days shows neutral average scores across 32 articles, spanning housing, crime, and transport — no clear pattern of positive or negative local coverage emerges from that sample.
