Well really AV will make little difference.
At the last election had we had AV, Conservatives would have likely got 281 seats(26 less than they did). Labour would have got likely 262 seats (4 more than they did), the Lib Dems would have got 79 likely(22 more than they did).
Still a hung parliament.
In the current polls in an election tomorrow, Labour would likely get a 65+ overall majority under fptp.
Under AV they would still get a 60+ overall majority on the current polling figures but the Lib Dems would only get about 12 seats currently under fptp but likely 30 to 35 under AV.

Such a small change that would only benefit the Lib Dems as to the voting system as AV would is, 1) not worth the bother of voting for it and 2) certainly not the worth the estimated cost of £250,000,000 for the referendum.

Full PR is a different thing but to waste so much time on this AV referendum is a waste of that time and the £250 million cost of it could be used better elsewhere.
