Polling on Thursday's elections

Today there was a new London poll from Opinium and a new Scottish poll from Survation. However with only two days to go before Thursday's elections I thought I would take a broader look at all the polling so far for this week's contests.

London

Four companies have produced polls for the London election this year: ComRes, YouGov, Opinium and Survation - their latest figures are below (Opinium publish their first round data without removing don't knows, so I've repercentaged it to make it comparable to other polling). Note that while Opinium described their poll as their final poll for the election, the polls from the other companies are not necessarily the final ones: I'm expecting to see some eve-of-election polls tomorrow.

The recent polls have Sadiq Khan convincingly ahead - the three most recent polls have him just short of winning on the first round, and on the second round he wins comfortably with a lead of 14 to 20 points. The ComRes poll is a little closer, but is a month old now and still had Khan winning by ten points on the second round. Note that only one poll, Opinium's final call, has been conducted since Labour's anti-Semitism row. Khan himself has thoroughly distanced himself from Ken Livingstone, but there is always a risk of guilt by association. Opinium's poll doesn't suggest it has damaged him (in fact it had Khan extending his lead) and Khan's lead looks unsurmountable anyway, but we'll see what the final polls tomorrow show.

Scotland

A broader range of companies have produced polls in Scotland, with figures from six different companies so far. Once again, these are by no means the final polls from each company and I am expecting final eve-of-election polls from some companies tomorrow.

The SNP's victory in Scotland is a foregone conclusion (hell, if they don't win this would be the king of all polling errors). The more interesting question is who will come in second place - Scottish Labour's stock has fallen so low they risk dropping behind the Scottish Conservatives. All recent polls now have Labour ahead of the Tories on the constituency vote, but several have the Conservatives ahead on the regional vote (and given that Labour will struggle to win constituency seats, the regional tally will likely have a greater impact on how many MSPs each party gets). Also keep an eye on the gap between the SNP's constituency vote and regional vote - in 2007 and 2011 they were within a percentage point or two of each other, but the polls are suggesting the SNP will do between five and seven points worse on the regional vote, largely to the benefit of the Scottish Greens. This seems feasible enough (the Scottish Parliament's electoral system means that if the SNP clean up on constituency seats they will struggle to win many list seats) but it will be interesting to see to what extent it is reflected in the actual results.

Wales

There is comparatively little polling in Wales and the only regular and recent figures are the YouGov polls for ITV Wales and Cardiff University (ably reported on by Roger Scully at his Elections in Wales blog). The most recent figures there are CON 19%, LAB 33%, LDEM 8%, Plaid 21%, UKIP 15% for the constituency and CON 19%, LAB 29%, LDEM 8%, Plaid 22%, UKIP 15% in the regional vote. There will be a final YouGov Wales poll on ITV news tomorrow night.

Northern Ireland

Despite the name of this blog, it actually tends to be GB Polling Report most of the time - Northern Irish polls are even rarer than Welsh ones. We do have one though! Lucidtalk had a poll of Assembly voting intention figures in the Northern Irish edition of today's Sun - topline figures are DUP 27%, SF 26%, UUP 16%, SDLP 12%, Alliance 8%, TUV 4%, GRN 3%.

Police and local elections

The other two elections on Thursday are local authority elections - mainly in those districts councils that elect by thirds, including metropolitan councils outside London (just over a third of the country will have local elections) - and Police and Crime Commissioner elections, which take place throughout England and Wales with the exceptions of London and Greater Manchester. Neither contest has any published polling.
