Brown's got this one horribly wrong:
There is now a stronger case than ever that MPs should be elected with the support of more than half their voters — as they would be under the Alternative Voting system. And so I can announce today that in Labour's next manifesto there will be a commitment for a referendum to be held early in the next Parliament it will be for the people to decide whether they want to move to the Alternative Vote.
Wrong system - ATV does not produce PR. Only the single transferable vote will do that. And the referendum should be next May - on the day of the general election.
His failure to pick winners continues - and he's now nearly out of time.
