Another polling company - Opinium Research - has published a poll today putting UKIP in third place, ahead of the Lib Dems.
The Opinium poll backs up YouGov's findings in yesterday's polling that UKIP have overtaken the Lib Dems. The data tables haven't been published which is a shame because it would be interesting to see the breakdown for the midlands and Wales which YouGov combines into a meaningless polling region.
