It hasn't been long since the last update of the Poll of Polls, but I think another one is probably in order, because the full-scale Survation poll has now dropped out of the sample, and there has also been an intriguing flurry of dreadful results for Labour in Scottish subsamples from Britain-wide polls. And when I say 'dreadful', I mean dreadful even by the standards of recent weeks and months. That may have happened by pure chance (ie. as a result of normal sampling variation), but it'll be well worth keeping an eye on the remaining YouGov and Populus subsamples this week to see if there's any further sign of public opinion hardening against Labour and the hapless Mr Murphy.
This update is based on eight Scottish subsamples - four from YouGov, one from Survation, one from ComRes, one from Ashcroft and one from Populus.
Scottish voting intentions for the May 2015 UK general election :
SNP 43.8% (+0.5)
Labour 23.9% (-2.7)
Conservatives 17.4% (+0.8)
Liberal Democrats 6.9% (+1.3)
UKIP 4.5% (+1.1)
Greens 3.3% (-0.2)
(The Poll of Polls uses the Scottish subsamples from all GB-wide polls that have been conducted entirely within the last seven days and for which datasets have been provided, and also all full-scale Scottish polls that have been conducted at least partly within the last seven days. Full-scale polls are given ten times the weighting of subsamples.)
