In the UK there was a vote on moving from the first past the post model. People didn't like it since it more often left the country with coalitions (which is apparently a Bad Thing).

To point out the rather obvious problem with FPTP is new parties struggle to make headway, candidates come from the small local parties and HQ divides the country into safe seats and swing seats. The former can be ignored and all policies should target people in the latter.

Protest voting is only possible by spoiling one's ballot paper or not bothering to go (neither really upsets the politicians). A system where votes are transferred does enable protests as well as votes not being "wasted" on an outsider.

I would like to see devolution to regional / local levels continue - but with the local candidates not allying themselves to a National party; and as a side note I would like to see the jobs from Whitehall move to the provinces rather than just adding more bloat to the system.
