Most recent election (2026)
In 2026, 50 seats were up across 50 wards. The table below shows what each party actually won — alongside what they would have won if the 50 seats had been shared in proportion to votes received (how, with caveats). The Δ column is the actual seat count minus the proportional seat count — positive numbers are parties First-Past-the-Post over-represented; negative are parties it under-represented.

Vote share vs seats won
The top bar is each party's share of votes cast in this council. Below, one square per seat, coloured by the party that won it — first the actual First-Past-the-Post result, then what a proportional method would have produced from the same vote totals. Divergence between the bar and the actual grid is the indictment of the method.
Council composition: what this election replaced
