Council composition as of 2025

Most recent election (2023)

In 2023, 61 seats were up across 28 wards. The table below shows what each party actually won — alongside what they would have won if the 61 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.

Ward by ward

Each row is a ward, each column a cycle. Each cell shows the top-of-poll candidate's party (swatch) and their share of valid ballots. Wards are matched by name across cycles — boundary reviews can mean a ward of the same name is a slightly different area in a later cycle.
