I think its all 'smoke and mirrors ' to get peoples attention away from the fact that governments economic policy has failed. The country itself is not big enough for this type of system unlike the United States where each state has its own congress/assembly. The only thing what might work is for each city to elect its own Mayor like London does Sheffield had a vote over this but rejected it. I think in Sheffield case people wanted to keep the Mayor as non political figure and for ceremonial duties.
