YouGov/Sun - CON 31, LAB 45, LDEM 10, UKIP 7

This morning's YouGov poll for the Sun has topline figures of CON 31%, LAB 45%, LDEM 10%, UKIP 7%. A fourteen point Labour lead is certainly not unprecedented (YouGov had them that far ahead back in June) and not outside the normal margin of error, but wouldn't be a bad boost from the Labour party conference.

More interesting are the changes to how Ed Miliband himself is seen. YouGov repeated a bank of questions about Miliband that were asked before the beginning of the party conference, and they show a positive change in public perceptions of Ed. The percentage of people who think he has made it clear what he stands for is up 12 points from 24% to 36% (49% think he has still not made it clear), the percentage of people thinking he is up to the job of Prime Minister is up 6 points from 25% to 31% (47% still think he isn't). There is more modest movement on whether he is seen as a strong leader, up three points from 16% to 19%, but it is still in the right direction.

On the fortnightly Best Prime Minister question Cameron still leads, but by a narrower margin - 31% think Cameron would be the best PM, 27% think Ed Miliband would be the better choice. While Ed’s ratings are significantly up, there are clearly still some reservations amongst Labour voters - still only 64% of Labour voters say Ed would be the best PM.

All in all, it appears to be a thumbs up for Miliband. It hasn't transformed public perceptions of Ed, but at the end of the day it would be unrealistic to expect it to, it has moved perceptions in the right direction for him. What remains to be seen now is whether it lasts, or whether it is the transitory effect of positive publicity.
