These are historical source tables. They are not the current membership list, a final certification record or a 2026 forecast. The book describes its figures as immediate election results.

A dash preserves a dotted book cell with no separate count. Allocations reconcile to 435 seats; missing source cells are not rewritten as reported zeroes. The web-table remainder is calculated as total minus party columns, without classifying it as a vacancy.
