YouGov/Sun - CON 35, LAB 45, LDEM 9

Tonight's YouGov poll has topline figures of CON 35%, LAB 45%, LDEM 9% - the Labour lead is back up to double figures.

This particular poll maybe something of an outlier, but even so, the apparent budget boost was certainly very short lived. Perhaps it was just the positive effect of the budget or Libya fading, or perhaps it was cancelled out by the march at the weekend. While the coverage of the march ended up being marred by the violence, it doesn't mean they didn't damage the government, in fact the two student protests last year that ended in violence also hit government support - though the poll effect is probably more from the reminder of unpopular policies and opposition to them, than the violence itself!
