Latest GB and London voting intentions

Two new GB voting intention polls over the last couple of days. Opinium in the Observer had topline figures of CON 33%, LAB 32%, LDEM 5%, UKIP 17%, GRN 4% (full tabs are here). Meanwhile BMG released some new GB voting intention figures today: their toplines are CON 36%(-2), LAB 31%(+1), LDEM 7%(+2), UKIP 16%(nc), GRN 5%(nc), and full tabs are here.

The last few polls we had (from ICM, YouGov, ComRes and Ipsos MORI) all had Labour and the Conservatives within a few points of each other. Opinium show a very similar picture, but while BMG do show the Conservative lead falling a little, they've still got a five point lead. At first glance I considered whether this could be due to fieldwork dates - perhaps as the negative coverage of the budget and IDS's resignation faded the Conservatives were recovering? It's not that though, the Opinium fieldwork is actually considerably more recent that the BMG fieldwork, which took place over Easter. Perhaps it's a methodological difference, or perhaps it's just normal random sample error - looking at the broad picture across all the pollsters it still looks as if the gap between Conservatives and Labour has closed right up to a few points.

There was also a new Opinium poll on the London mayoral election. First round voting intention figures are KHAN 35%, GOLDSMITH 27%, WHITTLE 3%, PIDGEON 3%, BERRY 2%, GALLOWAY <1%, DON'T KNOW/WNV 30%. Without don't knows that would work out at Khan 49%, Goldsmith 39%, Whittle 4%, Pidgeon 4%, Berry 3%, Galloway 1% - a solid lead for Sadiq Khan. After reallocating second preferences and taking only those 10/10 certain to vote, Opinium's topline figures are KHAN 54%, GOLDSMITH 46%. Full tabs are here.
