MP for Selby
Parliamentary Under-Secretary (Department for Transport)
“A party-loyal MP who rarely rebels and now holds a government role in transport.”
Keir Mather is the Labour MP for Selby, elected in 2023. He currently serves as Parliamentary Under-Secretary for Transport and has a background of parliamentary committee work and policy scrutiny, including roles on the Treasury Committee and the Holocaust Memorial Bill Select Committee; he has also served as an Assistant Whip.
He votes with his party on all recorded divisions (100% loyalty) but has a notably low voting attendance (18%), well below his party's average. His record shows support for workers’ rights and trade unions, and a tendency to oppose stricter immigration controls, asylum measures, and the Rwanda deportation scheme, while backing data protection and certain VAT changes.
Declares one financial interest: donations and other support (including loans) for activities as an MP.
