How Labour support for AV has waned
When the histories of the AV referendum are written - instant bestsellers, no doubt - the focus will be on the Labour vote.
In particular, the failure of Ed Miliband to give a strong lead to the pro-AV forces within the Labour Party, and above all the sudden switch among such a large section of the party.
Remember, it was actually Labour, not the Lib Dems, who first proposed the idea of a referendum on AV - in Gordon Brown's 2009 conference speech.
And remarkably, at an important meeting of the Parliamentary Labour Party (PLP) in early 2010 he got the policy through with just three MPs voting against. Yes, THREE.
OK, supporting a referendum on AV isn't quite the same thing as supporting AV itself, but they come pretty close.
Now we learn that 131 Labour MPs are signed up to the No campaign, more than half the PLP.
How the world changes.
