It's becoming increasingly hard to blog about opinion polls when I'm on the move, because the datasets won't always load on my mobile phone (the YouGov website has become particularly hopeless since it was redesigned). Hence the delay in posting a post-Ipsos-Mori Poll of Polls update, but here it is at last. It's based on two full-scale Scottish polls (from Survation and Ipsos-Mori), plus eight Scottish subsamples - four from YouGov, one from ICM, one from Ashcroft, one from TNS-BMRB and one from Populus. The full-scale Panelbase poll has now dropped out of the sample, which is part of the reason for the huge increase in the SNP's lead.
Being able to include a poll from TNS-BMRB makes this something of a red letter day, because their numbers are usually too far out of date, even on the day of publication!
No percentage change is listed for the Greens, because I wasn't able to include them in the last update.
Scottish voting intentions for the May 2015 UK general election :
SNP 47.1% (+4.2)
Labour 25.6% (-2.4)
Conservatives 14.3% (-0.7)
Liberal Democrats 5.5% (+0.5)
UKIP 2.5% (-2.9)
(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.)
