Sources close to The Guardian are indicating to me that their poll tomorrow will show a Tory lead of three points. If that is true (and I have no way of verifying it at the moment), and the YouGov poll for the Telegraph shows a similarly dramatic turnaround, then it would surely mean that all election bets are off. It doesn't indicate how Brown will explain the volte face, but that is something for us all to look forward to and relish.
UPDATE: I've just been told the Channel 4 News/YouGov poll shows a Labour lead of 3% - again, a massive turnaround. I'm trying to verify these figures at the moment, but I thought you'd all want to know, even if they are at the moment unconfirmed.
UPDATE 4.40pm: Well the plot thickens. The Guardian figures were apparently from the early results, but Labour have now firmed to hold a small lead, which is thought to be nearer to the Channel 4 figures.
Whatever the figures finally turn out to be, it's quite clear there has been a dramatic shift in the polls over the last five days. As I said some months ago, it will be difficult to really read the polls properly until a few weeks time. Gordon Brown should have realised that before he marched everyone up the election hill. Perhaps he's not quite the supreme strategist that everyone thought.
All good fun, eh?
