I hear Labour whips are very worried about losing Tuesday's vote on changing the voting system to the Alternative Vote system. With a majority of more than 60, they ought to win the vote comfortably, but doubts are being expressed about how a significant number of Labour MPs will vote. Very few are AV enthusiasts and there are plenty who reject any hint of any kind of electoral reform. Others, especially those who are standing down, may well just decide not to bother turning up.
In addition, the LibDems have published their own amendment to the motion. They hate AV. They don't regard it as in any way proportional. It is therefore likely they will abstain, but if their amendment is treated with contempt, they could join the Tories in the no lobby. The Tories are on a three line whip, with dire warnings being issued to those who think they might have an evening off.
Another Gordon Brown idea that seemed like a good wheeze at the time?
