South Cambridgeshire 2026
Local elections held 7 May 2026.
How to read this page
Each race below shows the share of valid ballots the marginal elected candidate actually won, and compares it to the proportional quota: the share they'd need to clinch the seat under any proportional voting method (1 seats + 1). For a 1-seat ward the quota is 50%; for 2 seats, 33.3%; for 3 seats, 25%.
Where the actual winning share fell below the quota, we show the signed gap as points below quota (a negative number) — the editorial indictment. Above-quota results clear the bar and pass without comment. The voting method is the subject of every observation here. Named candidates appear as the public election record requires; the cause being audited is the voting method, not the individuals. See the methodology page for derivations.
If votes were counted by party
Across the 7 wards in this cycle, parties received the vote totals below. The proportional column shows what each party would have won if the 10 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.

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
