Same votes, different counting rule
Compare the seats Reform UK actually won under FPTP with a proportional re-count of the same council-level votes. Positive means seats unfairly awarded by FPTP; negative means seats the party was denied by FPTP.
Where the seats came from
Per-council net seat change vs each council's prior appearance in our dataset (typically that council's previous all-out election or its last by-thirds slice). "Debut" rows are councils whose first cycle in our window is 2021 — usually the result of a boundary reorganisation or being a county outside our 2021 LEH coverage.
Seats gained (0 councils)
No councils where seat count rose vs prior cycle.
Seats lost (0 councils)
No councils where seat count fell vs prior cycle.
Debut councils (86)
Net-change comparisons are versus each council's most recent appearance in our dataset (2021–2026). For all-out councils that's the previous all-out cycle (typically four years prior); for by-thirds councils it's last year's slice. Cross-cycle ward boundary changes can produce small artefacts — see methodology.
