Each row is one party. The bar shows how its MPs voted relative to a neutral midpoint — to the right = on-side with the majority position, to the left = opposed. The percentage figure is the share of that party’s MPs who took the same side: higher = more whip-disciplined, closer to 50% = a freer vote.

Pending — issue-to-service mapping
Mapping each Westminster issue to the equivalent council service bucket (so “Taxation” → the matching service line on council finance, with the ranked-spend table this section wants) is its own taxonomy job. Council service spend lives on the council pages today; cross-cut by issue here in a follow-on pass.
