I'm a resounding NO!!! It is an extremely messy way of getting a parliament.There are a lot of people elected by default. Interestingly of the 3 countries that operate this system one, Fiji are going to scrap it and the Australians would dearly love to, if surveys are to be believed.
My great worry is that the Populace that voted the Labour party into power, not just once but thrice - even knowing what shenanigans the Government was up to at the time - will vote yes..........if they can sleepwalk through that, they can sleepwalk into AV. God help us !!!!!
