YouGov/Sun - CON 32, LAB 42, LD 8, UKIP 12

The Sun have tweeted out tonight's YouGov poll - topline figures are CON 32%, LAB 42%, LD 8%, UKIP 12%. This is somewhat at odds with the Labour leads of two, three and three points so far this week, though for what it's worth all four polls would be within the normal margin of error of CON 34, LAB 39, LD 9, UKIP 12, the average of this week's figures.

When an unusual poll comes along I personally rather discount it - more often than not it'll just be a blip. When the same happens two days in row it gets my attention, but I wouldn't conclude anything. When you get three in a row I normally take it seriously, it looks as though something is afoot.

But it can still just be random chance. Right now we don't really know what the position is. It could be that tonight's poll is an outlier and other polls will continue to show lower leads. Alternatively it could be that actually nothing's changed and its all just been random variation around the six point lead we've had for months. As ever, time will tell.
