  • “No vote recorded” is not the same as absent: leave, illness and chairing the sitting look the same.
  • A group’s line is inferred from its members’ votes — Parliament publishes no whip.

Voting neighbours

Members who voted the same way most often in the roll calls they both took part in, within and outside the member’s group (group at the date of each vote), over all roll calls of the term.

At least 200 shared roll calls over at least six months in office together. Within = both sat in the same group on the date of the vote; a member who changed group can appear on both lists. Baseline = the median agreement of all pairs of members of the groups the two sat in on the date of each shared vote (within: the group they shared; outside: the two groups), weighted by the votes they shared in each combination.

Within ECR

Agreement: roll calls where both cast the same position, of the roll calls both voted in while in the same group (“shared”); a count below 50 shared. Baseline: the median agreement of every pair of members of that group.
