Most recent election (2022)
In 2022, 46 seats were up across 39 wards. The table below shows what each party actually won — alongside what they would have won if the 46 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 | 15,947 | 38.0% | 18 | 39.1% | 18 | 39.1% | 0 |
| Labour Party | 15,157 | 36.1% | 22 | 47.8% | 17 | 37.0% | +5 |
| Independent | 5,262 | 12.5% | 5 | 10.9% | 6 | 13.0% | -1 |
| Liberal Democrats | 3,417 | 8.1% | 0 | 0.0% | 3 | 6.5% | -3 |
| Green Party | 2,063 | 4.9% | 1 | 2.2% | 2 | 4.3% | -1 |
| ND | 163 | 0.4% | 0 | 0.0% | 0 | 0.0% | 0 |

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.
