One of the more active Northern Ireland MPs at Westminster, Eastwood attracted attention in late April when she backed referring Prime Minister Starmer to the Privileges Committee over his statements on Peter Mandelson's appointment -- a vote that put her alongside the opposition against the government. She also voted to carry over the Northern Ireland Troubles (Legacy and Reconciliation) Bill, supporting its continuation into the next session. Earlier in the year, she backed removing the two-child Universal Credit limit, supported extending carbon pricing to maritime shipping, and split her votes on children's digital safety: backing a statutory mobile phone ban in schools while opposing an outright under-16 social media ban.

Her participation rate is low -- she has voted in roughly one in eight divisions -- though this partly reflects the position of Northern Ireland parties, which frequently abstain on England-only matters. Where she does vote, she has aligned 100% with Alliance colleagues, with no rebel votes on record. Her 105 parliamentary contributions across 72 debates is the more telling measure of engagement: she speaks frequently on the economy and jobs, social care, health, and cost-of-living. Stance data shows consistent opposition to benefit cuts and the employer National Insurance rise, alongside strong alignment with climate action measures.

Eastwood sits on the Northern Ireland Affairs Committee, a natural fit given her constituency. Local news coverage over the past 90 days has centred on cost-of-living and community issues, and she has drawn positive national attention -- including a Backbencher of the Year nomination in December 2025 -- for constituency casework and campaigning, including an Early Day Motion on Royal Mail service failures and roundtables supporting local hospitality businesses. Overall voting data covers 62 divisions since July 2024.
