Most recent election (2023)
In 2023, 54 seats were up across 23 wards. The table below shows what each party actually won — alongside what they would have won if the 54 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.
| Party | Votes | Vote % | Seats won | % of seats | Proportional seats | Proportional % | Δ |
|---|---|---|---|---|---|---|---|
| Conservative Party | 34,319 | 40.6% | 20 | 37.0% | 23 | 42.6% | -3 |

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.
