Labour had a bit more then a third of the votes, which is pretty close to were Reform is polling today. However Labour won a massive majority with those votes. If Labour wants to prevent a Reform victory they need to change the election system. It is even worse for the Tories. So long term Tory supporters will cheer them on.
Looks like they plan to introduce some sort of change in the next parliament session.
Wales just moved from first past the post to proportional under a Labour government in the Senedd.
