There's a remarkable new ComRes/ITV poll out which shows that support for the Lib Dems has risen fourteen points to 35 per cent on the back of Nick Clegg's performance in last night's TV debate.The poll puts the Tories up one to 36 per cent, with Labour down five to 24 per cent.
Those figures would leave support for the "others" at just 5 per cent, which suggests that the Lib Dems are scooping up the anti-politics vote.
But before we all got too excited about the possibility of Nick Clegg entering Downing Street, it's important to note that this was a poll of 4,000 people who watched the show last night.
As such, it's highly unreliable and cannot be described as representative (what about the millions who didn't watch the show?). But it does confirm two things. First, that Nick Clegg was the big winner from last night and second, that voter loyalty is much weaker than it used to be.
UPDATE: ComRes have just released some new national figures, which take into account the 30 million or so voters who didn't watch the debate. The poll has the Tories unchanged on 35 per cent, with Labour down one to 28 per cent and the Lib Dems up three to 24 per cent.
