Defence and Foreign Affairs.
Military, national security, and international relations
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.
