Sadie Smith has an interesting post on the Total Politics blog today where she highlights how even if there is a "Yes" vote in the AV referendum that Conservative MPs would still have the chance to thwart a change to the voting system. She explains how because AV can only be implemented if the new boundary changes are voted through that were that legislation to be voted down, AV would not come in:
Imagine that AV has been backed by a narrow majority in the referendum, on a very low turnout. For many Tories, especially David Cameron, that’s a nightmare scenario. In those circumstances, would he be able to convince his own side to trigger the implementation of AV by voting through new boundaries?Don’t forget, the Tories aren’t expected to get off scot-free when the Commission presents the new constituency map; at least thirteen Conservatives look set to lose their seats, and many more will be expected to campaign within vastly changed boundaries with no guarantee of success, especially under AV.Come 2013, the price that Tory backbenchers are being asked to pay in order to keep Nick Clegg in Ministerial cars might begin to look a tad high. They would have the power to stop the introduction of AV by voting down the implementation of the new boundaries, if they joined forces with Labour. That would surely be a coalition breaker, but it’s not inconceivable.
