Three Rivers 2023
Local elections held 4 May 2023.
Each race compares the marginal winner's share of valid ballots to the proportional quota — the share they'd need under any common proportional method. How the numbers are derived →
If votes were counted by party
Across the 13 wards in this cycle, parties received the vote totals below. The proportional column shows what each party would have won if the 14 seats had been shared out 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 |
|---|---|---|---|---|---|---|---|
| Liberal Democrats | 9,940 | 41.9% | 8 | 57.1% | 6 | 42.9% | +2 |
| Conservative Party | 7,701 | 32.5% | 4 | 28.6% | 5 | 35.7% | -1 |
| Labour Party | 3,300 | 13.9% | 1 | 7.1% | 2 | 14.3% | -1 |
| Green Party | 2,789 | 11.8% | 1 | 7.1% | 1 | 7.1% | 0 |
| Total | 23,730 | 100.0% | 14 | 100.0% | 14 | 100.0% | 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.
Council composition: what this election replaced
Two opencouncildata snapshots: the council immediately after the 2023 election (current) and immediately before it (2022). Only ~⅓ of seats were contested in 2023 — most of the bench is unchanged, and the cycle's effect on the overall composition is what shifts.

This is a 2-seat ward under bloc vote — each voter could cast up to 2 votes, so summing candidate votes overcounts voters by ~2×. We show share of votes (matches the council's published figure) and share of voters (est.) (raw share × 2, the figure comparable to the proportional quota). Why two columns →
| Rank | Candidate | Party | Votes | Share of votes Candidate votes ÷ total votes cast in this ward. Matches the share the council publishes. | Share of voters (est.) Estimated share of voters who supported this candidate, comparable across single- and multi-seat wards. Each voter could cast up to 2 votes, so we approximate ballots as total votes ÷ 2. This is the figure compared against the proportional quota. | Below quota Each elected candidate's share of valid ballots minus the proportional quota for this race.
