Changing the voting system would change the country

I know this is the third blog post today, but I decided to check the papers and blogs before bed...

This excercise opened up a thought process in my mind. If we change the voting system, would the british political environment change?

The answer is probably yes! In Britain we have a distinct party political system. This is a deep set historical system. Yet the 2010 election delivered a hung parliament, possibly contributed to by the televised debates. The coalition of the conservatives and lib dems was subsequently formed.

Under AV the lib dems would have gained a further 22 seats. Throwing the election even more wide open.

So will AV replace single party governance with coalition governance forever?
