Methodology
Voting participation is the percentage of eligible Commons divisions an MP voted in. A division is eligible for an MP if it occurred on or after their Commons membership start date. Divisions before the MP entered Parliament are excluded from both numerator and denominator.
Lowest participation excludes MPs with fewer than 10 eligible divisions to avoid penalising very recently elected members.
Most and least recorded votes rank current MPs by raw vote count in eligible divisions. The least-votes ranking also excludes MPs with fewer than 10 eligible divisions.
Commons average is the mean participation rate across all current MPs with at least one eligible division.
Party engagement is calculated from all current MPs in a party group: total recorded votes divided by total eligible divisions for those MPs.
Most likely to rebel ranks MPs by the percentage of their votes that went against the majority of their party group. MPs with fewer than 50 votes are excluded. Independent and Speaker roles are excluded because they do not have a party whip.
Service length is based on the Commons membership start date imported from the Parliament Members API.
Roles include government posts, opposition posts, and committee memberships from Parliament biography data.
Interest categories count the number of distinct registered interest categories, not individual items.
