UKIP are 1% behind the Lib Dems again in tonight's YouGov poll on 8%.
The Lib Dem vote in London has rallied with them on 15% with UKIP dropping to 5%. UKIP and the Lib Dems are level pegging in the south of England and the midlands/Wales polling regions and ahead of them in the north of England. The Greens have jumped to 6% in London, perhaps indicative of the BBC's shameful electioneering on their behalf.
