With such a fragmented vote, it seems a shame that the parties can't split the different jobs between them. Labour could run the public services such as schools and hospitals, the Tories could look after crime, immigration, defence and foreign affairs and the Lib Dems could have the environment and whatever else is left! Then the three parties could get together to decide on the ecomony stuff under the guidance of the Bank of England!
As the parties are becoming so much closer in policies and outlook, it would seem to make sense!
