Big post-conference boost for Labour

The first poll conducted since Gordon Brown's speech has some good news for Labour. The YouGov poll for the Sun has topline figures of CON 41% (-3) LAB 31%(+7) LDEM 16%(-4). It was conducted on Tuesday and Wednesday, with the fieldwork starting after Brown's speech.

The poll shows an impressive 7 point jump in Labour's support, putting them over 30 for the first time in months and resulting in the lowest Conservative lead since way back in April (though perhaps it's a sign of how much things have changed that a poll showing the Conservatives 10 points ahead is now considered a fantastic advance for Labour).

Does this mean the corner has turned and Labour are pulling things back? It could do - nothing's impossible - but right now it's probably more likely to be a passing conference boost. To see how ephemeral they can be we only need to look at the Lib Dem score in this poll. The YouGov poll conducted after their conference put them up 4 points to 20%, their highest score for years. This poll puts them back down at 16%, where they were before the conference season began. We'll know the real position after all three conferences and all three conferences bounces have come and gone.
