Warwick and Leamington.

A 100% party-line voter with no rebel votes, Matt Western's most notable recent work sits outside the division lobbies. As Chair of the Joint Committee on National Security Strategy, he led a public call in March for the government to provide greater clarity and detail on its national security plans -- a constructive but pointed use of his committee role to press ministers. He also wrote in The Guardian defending Keir Starmer's approach to the Middle East, and has been visibly active on Ukraine: paying public tribute on the fourth anniversary of Russia's invasion, personally participating in aid convoys, and criticising Warwick District Council as "deeply troubling" after it removed a Ukrainian flag from public display.

His parliamentary participation sits at 71%, somewhat below the Commons average. He votes firmly with Labour on workers' rights and progressive taxation, but deviates from his party colleagues on criminal justice reform -- backing it far less often than the Labour average -- and on pension protection, where he also falls well below the party norm. He speaks frequently, with over 180 contributions spanning the economy, defence, local government, and energy, reflecting his committee brief on economic security and arms export controls.

Western sits on the Business and Trade Committee and its sub-committee on economic security, which explains much of his speech activity around defence-industrial policy and trade. Local news coverage -- spanning 95 articles in the past 90 days -- has been most prominent on defence and economy issues. Bio data and full debate transcripts are available; vote-level detail on some 2026 King's Speech amendments is limited by the absence of published debate excerpts.
