The BBC Projected National Share of the vote just announced is Con 29, Lab 31, LD 13, UKIP 17, Others 10.

The PNS is an attempt to estimate what the share of the vote would be if the whole of GB had local elections and if the three main Westminster parties had fielded candidates in all wards, as they do in general elections. For more details see here and here.

Graphs below show how it compares with previous figures and polls historically.
