Tonight’s YouGov poll shows the Lib Dem boost continuing. The topline figures are CON 32%(-1), LAB 26%(-3), LDEM 33%(+4), so following on from BPIX yesterday we now have YouGov putting the Lib Dems in the lead. The 32% is the lowest the Conservatives have been with YouGov since the election-that-never-was in 2007, 26% is the lowest Labour have been since the Conservative party conference boost last year.

The poll was conducted on Saturday and Sunday, so with the “Lib Dem breakthrough” dominating the media and the election narrative. It’s quite hard to guess what is going to happen next – on one hand the Lib Dems are likely to face a concerted attack from the other parties and hostile newspapers, on the other hand if they stay at this level there will be a snowballing effect of them being seen to be on a roll, the Lib Dem’s normal weaknesses of being seen as a wasted vote will be whittled away, and if the two main parties start focusing their fire upon the Lib Dems it may well backfire by making them seem negative and the Lib Dems as the real challenger.
