Changes 2025–2029

Roman Bank & Peckover by-election

The by-election was triggered by the disqualification of Reform councillor Andy Osborn, after he was convicted of publishing a false claim about a rival candidate.

In an unusual development, about a week before the election the Green candidate announced he no longer wished to stand. However, the date for withdrawal had passed so his name remained on the ballot.

Ramsey & Bury by-election

The by-election was triggered by the resignation of Reform councillor Jim Sidlow, who cited personal and family pressures.
