Portsmouth North.
Labour Party MP Amanda Martin holds the seat on 34.9% of the vote.
1 Jun 2026
Steady and local-focused, Amanda Martin has no rebel votes to her name since entering Parliament in 2024 -- she has voted with Labour on every recorded division, including recent votes to tighten asylum support rules, back ministerial powers over pension fund investment, and oppose referring Keir Starmer to the Privileges Committee. Her most visible recent work has been constituency-facing: she is credited with helping secure £40 million from a government fund for Portsmouth, backing a £1 million boost for a veterans outreach centre, and championing a £1.56 million SEND investment after hosting ministerial visits and holding roundtables with local headteachers and families.
Her participation rate of 86% sits above the Commons average. She votes in line with Labour on workers' rights and progressive taxation, but her stance profile shows more distance from the party on climate action (44% aligned versus a party average of 52%) and welfare expansion (45%). She scores notably higher than her Labour colleagues on parliamentary scrutiny votes -- 25% aligned versus a party average of 6% -- suggesting occasional, if limited, instinct toward holding the executive to account, though this has not translated into open rebellion.
Her 331 contributions span economy and jobs, defence, local government, social care, and crime -- topics that reflect Portsmouth North's profile as a naval and working-class constituency. News coverage over the past 90 days skews positive where her name appears, with the strongest stories tied to education and local investment. Her committee roles -- the General Cemetery Bill and the Norwich Livestock Market Bill -- are minor and procedural. No significant negative press coverage is recorded.
