YouGov/Sun - CON 37%, LAB 42%, LDEM 9%

No sooner I write comments about things appearing to settle into a pattern of Con & Lab neck and neck it is almost inevitable a poll will come along to contradict me. Such is life! Anyway, tonight's YouGov poll for the Sun has topline figures of CON 37%, LAB 42%, LDEM 9% - the highest Labour lead YouGov have shown since before David Cameron's veto in December.

Usual caveats about any poll showing unusual movements apply - sure, it could be a sign that the narrowing of the polls has passed and we are headed back to the Labour leads of 5 points or so that we got used to last autumn... or it could be normal sample error, and we'll be back to neck-and-neck tomorrow. Right now we can't tell.
