UKIP and Lib Dems level again in YouGov poll

UKIP is level pegging with the Lib Dems again in tonight's YouGov poll.

Both UKIP and the Lib Dems are on 9% overall with UKIP out-polling the Lib Dems in the south of England and YouGov's Midlands/Wales polling region.

The combined vote share of the SNP, Plaid Cymru, BNP, Greens, Respect and "other" is only 9% which begs the question, once again, why do YouGov still lump UKIP in with the "others" when clearly it isn't?
