Three ordinary council cycles, with the valid 2024 Lengua replacement completing its 2023 cycle. The 2016 national vote and ballot totals now reconcile. Councillor and alderman seats stay separate. Ward ballots overlap these corporation aggregates; do not sum votes across the two levels. Subsequent by-elections and current control remain to be verified.
