Recorded-vote participation: The share of recorded votes (divisions) they were eligible for in which they voted, across their full record on They Vote For You. Divisions are only part of parliamentary work. “Voted with party majority” counts votes where they voted the same way as most members of their party.

How they voted on policies

Each policy groups related divisions. Counts are this member's recorded votes from 4 July 2019 to 24 June 2026; the score is They Vote For You's weighted agreement across all years. A voting record shows how someone voted, not necessarily what they personally believe.
