Newid- before writing this post but none has been forthcoming so here goes anyway.
Newid is proposing a government for Wales based on the principles of Demarchy. Their blog can be found here and an article on their project can be found here on the OurKingdom site: Demarchy – can the people rule?
Demarchy is a system by which ordinary citizens are selected at random to form citizens' juries that decide issues of public policy. Exactly as a jury is chosen for a criminal case but this time constituted to govern the country.
A party campaigning for a system that will kill off political parties! That's got have something going for it.
