Tonight’s YouGov poll for the Sun has topline figures of CON 31%, LAB 44%, LDEM 8%, Others 17% (including UKIP on 8%). Thirteen points equals the biggest Labour lead YouGov have shown since the election (it’s been hit twice before, both in April).
All the normal caveats apply – sure, it could be the start of larger Labour leads or it could just be normal random variation around the 10 or 11 point leads we’ve been seeing of late. That said, I personally wouldn’t be surprised if we did see bigger Labour leads in the coming days, it is far from unknown for local election victories to give parties a boost (from having the aura of success about them and “looking like a winner”). Equally, it’s far from guaranteed to happen. As ever, time will tell.
