Good news! Reversing the mayoral and PC changes were just in the news last week! https://www.theguardian.com/politics/2025/jul/10/ministers-propose-voting-changes-for-mayoral-elections-in-devolution-bill

Seeing as they are following in the footsteps of the Welsh voting reforms with this news, I would hope that if all goes well then they will follow with the PR changes too. Although looking polling at how Labour are expected to fare in the Sennedd, maybe they will consider it not in their interests.
