MP for Buckingham and Bletchley
“Centre-left Labour MP with high party loyalty, unusually low attendance, and a single rebellion on an end‑of‑life Bill.”
Callum Anderson is a Labour and Co‑operative MP for Buckingham and Bletchley, first elected on 4 July 2024. He has served on committees for the Pension Schemes Bill and the Data (Use and Access) Bill, and sits on the centre-left of the political spectrum. He has a notably low voting attendance and one recorded rebellion against his party.
Mr Anderson has voted with his party in every recorded division (100% party loyalty), but his parliamentary attendance is 16%, well below the party average of 33%. He has a single rebel vote. His record shows support for workers’ rights protections and trade union powers, and for renters’ protections, while he has opposed transgender rights and mental health service funding, and has a mixed approach to Universal Credit and climate change measures.
Declared financial interests include gifts, benefits and hospitality from UK sources (three entries).
