Ranked 141 of 638 MPs for attendance. The median of MPs who vote is 72.3%. Ministers and front-benchers vote less often than backbenchers for reasons of office rather than absenteeism, and Parliament does not publish reasons for any absence — the ranking is a starting point for a question, not an answer to one.
