very bouncy. I think there was an uptick for the Tories a week or so ago but it seems more temporary than they would have wanted. Most up-to-date polls seem to have reverted to what they were before the net-zero-related announcement with a couple of 20%+ leads for Labour amongst them.
It's bouncy but not unlike some other polls in the last couple of days. It would be usual for the Tories to enjoy some sort of Conference bounce thereafter. They certainly need one. I agree that it's random sample variation rather than a real increase in Labour's lead, or real decrease in previous polling. I tend to think that for the last few months there hasn't been that much volatility in the real, as opposed to polling, world.
