Shadow Welsh secretary Peter Hain wants the Welsh Assembly elected by first-past-the-post rather than the proportional additional member system,. "The only acceptable option given the AV referendum result is to have all AMs elected by first-past-the-post, and we believe that each of the 30 new constituencies should elect two AMs by that system," he says.
Hain is generally a good thing, but this is reactionary Labour tribalism of the worst kind. (Labour would do much better in Wales under FPTP, probably so well that it would become a permanent ruling party.) The result of the AV referendum was in no sense an endorsement of first-past-the-post, and – contrary to Hain's claims – there is no evidence that Welsh voters find AMS too complicated. The system has worked well in both Wales and Scotland, and there's a strong case for using it for Westminster elections too.
