Two new polls today:

Survation for Good Morning Britain this morning had topline figures of CON 43%(nc), LAB 37%(+3), LDEM 9%(nc), UKIP 4%(nc). Fieldwork was on Friday and Saturday and changes are from the previous week. Tabs are here.

ICM for the Guardian had topline figures of CON 45%(-1), LAB 33%(+1), LDEM 8%(nc), UKIP 5%(nc). Fieldwork was from Friday to Monday and changes are from the ICM/Sun on Sunday poll at the weekend. Tabs are here.

Both of today’s polls continue to show movement in Labour’s favour, thought the overall lead is different. A six point Tory lead would represent a small swing towards Labour, a twelve point Tory lead would still give them a stonking great majority.

The key difference between polls showing large and small leads is, as I wrote at the weekend down to how pollsters are treating turnout. There are lots of differences between different polling companies methods: they sample differently, weight by different things, do different things with don’t knows and so on. However, right now the one really huge difference is turnout. Weighted with all its normal demographic and political weights, ICM would have shown a Tory lead of only 3 points – that was transformed into a lead of 11 points by the turnout model, which predicts how likely respondents are to vote based on the estimates of turnout by age and class at the last election (the change from 11 to 12 points was the reallocation of don’t knows). That’s a big change, but given the errors in the polls in 2015 that may be necessary. On the other hand, if Jeremy Corbyn has managed to enthuse young people and there is a higher rate of turnout among younger voters than in 2015 then it risks understating Labour support. We shall find out next week…


Saturday night polls

We should have a truckload of polls tonight. There is a new Opinium, a new ComRes for the Indy & Sunday Mirror, YouGov for the Sunday Times, probably an ORB and perhaps an ICM for the Sun on Sunday. I’ve seen rumours of Survation too (they normally poll for the Mail on Sunday) and we’re overdue a Panelbase poll. The thing to look for is whether polls continue to show a narrowing of the Conservative lead – keep an eye on the fieldwork dates, more recent polls could be showing an impact from reactions to the bombing (or, indeed, the effects of the dementia tax row fading). Also remember the house effects I wrote about earlier – ICM and ComRes tend to show larger Tory leads anyway, so even if they show a significant movement towards Labour it may still leave the Tories with a good lead.

The first poll we actually have figures for is Opinium, who have topline figures of CON 45%(-1), LAB 35%(+2), LDEM 7%(-1), UKIP 5%(nc). Changes are from the previous week and fieldwork was on Tuesday and Wednesday, so just after the Manchester bombing but before political campaigning had resumed. We have movement towards Labour, but the Conservatives still managing to cling onto a double-digit lead. Tabs are here.

ComRes for the Sunday Mirror and Independent have topline figures of CON 46%(-2), LAB 34%(+4), LDEM 8%(-2), UKIP 5%(nc). Changes are from a fortnight ago, and fieldwork was between Wednesday and Friday. The Tory lead has dropped by six points, but ComRes tends to give the Conservatives some of their better figures, so this still leaves them with a twelve point lead. Tabs are here.

ORB for the Telegraph have topline figures of CON 44%(-2), LAB 38%(+4), LDEM 7%(nc), UKIP 5%(-2). Changes are from a week ago and fieldwork was Wednesday to Thursday. Once again, we have a narrowing of the Tory lead, in this case down to six points.

YouGov for the Sunday Times have topline figures of CON 43%(nc), LAB 36%(-2), LDEM 9%(-1), UKIP 4%(nc). Changes are from the Times poll earlier in the week and fieldwork was Thursday to Friday. This is the most recent of the polls we’ve seen so far tonight, and it has Labour falling back a bit from the YouGov poll in the week. That said, it is only one poll, so don’t read too much into that unless we see other polls showing a similar pattern.

ICM for the Sun on Sunday has toplines of CON 46%(-1), LAB 32%(-1), LDEM 8%(-1), UKIP 5%(+1). Fieldwork was on Wednesday to Friday, and changes are since the ICM/Guardian poll conducted over last weekend. Changes here seem quite steady (ICM’s previous poll already showed a sharp narrowing of the lead). As I said earlier, ICM and ComRes tend to show the largest Tory leads because of their demographic based turnout model.

I’ll update this post through the evening as other polls appear.

There have been two new polls out today – both show a sharp reduction in the Tory lead.

The weekly ICM poll for the Guardian has topline figures of CON 47%(-1), LAB 33%(+5), LDEM 9%(-1), UKIP 4%(-2), GRN 2%(-1). The Conservative party’s support drops only a little, but Labour jump up five to 33% (their highest since June 2016 according to Martin Boon). The fourteen point lead is larger than most other polls – this is for methodological reasons (ICM’s demographic based turnout model gives a large boost to the Conservative party, otherwise it too would likely have been producing a single-digit lead). Note that ICM have also tweaked their method slightly to hide the option of UKIP for respondents in seats where UKIP aren’t standing, though this will likely have only a small effect. Full tabs are here.

Meanwhile a Survation poll for Good Morning Britain has topline figures of CON 43%(-5), LAB 34%(+5), LDEM 8%(nc), UKIP 4%(nc). Changes are from the previous Survation telephone poll a week ago, rather than their online poll at the weekend. Full tabs are here.

Fieldwork for both polls was over the weekend, after the Conservative manifesto launch. While there was already a general movement towards Labour before the manifestos, the post-manifesto polls suggest a further and sharper movement since then. I wrote a while back about how manifestos rarely have much impact in general elections – while it’s impossible to prove a causal link, the timing certainly suggests this is an exception! Perhaps it’s because when elections are five years in the making most policies have already been announced and focus-grouped into things that won’t scare the horses. Or perhaps just because manifesto launches rarely go as wrong as the Conservative party’s appears to have.

Whatever the reason, the question now is whether this is a temporary narrowing that will reverse when (or if) the focus of attention moves onto other subjects, or whether we are heading for a somewhat tighter race than many people expected.


Two new voting intention polls today. The first by Survation for Good Morning Britain had topline figures of CON 48%(+1), LAB 30%(nc), LDEM 8%(+1), UKIP 4%(nc). Clearly there is no substantial change since their poll a week ago. Fieldwork was conducted on Friday and Saturday, after the leak of the Labour manifesto, and doesn’t show any sign of any impact.

The second was the weekly ICM poll for the Guardian. Topline figures there are CON 48%(-1), LAB 28%(+1), LDEM 10%(+1), UKIP 6%(nc). As many have noted, ICM are now are, along with TNS, one of only two pollsters still showing Labour support below thirty points (MORI last poll did the same, but that was several weeks ago when everyone showed Labour that low). It’s not that ICM haven’t shown Labour support rising a little. ICM have been showing Labour recovering slightly, it’s just they’ve been doing so at a slightly lower figures: at the start of the campaign ICM had Labour at 25-26% and they now have them at 27%-28%.

This seems to be a consistent methodological difference. The methodological differences between pollsters are complicated and various, and some of them work in opposite directions (ICM, for example, also reallocate don’t knows in a way that helps Labour) but the most obvious one at the moment is probably the approach to turnout. Traditionally British pollsters have accounted for people’s likelihood to vote by getting respondents to estimate their own likelihood to vote – put crudely, they ask people to say how likely they are to vote on a scale of 0 to 10, and then either weight them accordingly (someone who says they are 8/10 likely to vote is only counted as 8/10ths of someone who says 10/10), or apply a cut off, ignoring people who rate their chances below 5/10 or 9/10 or 10/10. Since 2015 several companies, including YouGov and Ipsos MORI, have also factored in whether people say they have voted in the past, weighting down past non-voters.

ICM and ComRes have adopted new approaches. Rather than basing their turnout model on people’s self-reported likelihood to vote, they base it on their demographics – estimating respondent’s likelihood to vote based on their age and social grade – the assumption being that younger people and working class people will remain less likely than older, more middle class people to vote. This tends to have the effect of making the results substantially more Conservative, less Labour, meaning that ICM and ComRes tend to produce some of the biggest Tory leads.

ICM’s weekly poll for the Guardian has topline figures of CON 49%, LAB 27%, LDEM 9%, UKIP 6%, GRN 3%. This is the first poll we’ve seen since the local government elections, and has the Tories back up to a lead of 22 points (indeed, according to Martin Boon it’s the Conservatives’ highest share from ICM since 1983). It wouldn’t surprise me if the Tories did get a boost from their local government success, but we shall see if it is echoed in other polls. Full tables are here.

Also out today was a new YouGov poll of Welsh voting intentions, conducted for ITV Wales and Cardiff University. Topline figures there are CON 41%(+1), LAB 35%(+5), LDEM 7%(-1), Plaid 11%(-2), UKIP 4%(-2). The previous YouGov Welsh poll was the one with that startling ten point Tory lead, conducted when the general election had only just been called and GB polls were showing twenty-plus point leads. In that context, the narrowing of the Tory lead may be partly a reversion to the mean after the unusual result in the last poll, may be partially a reflection of the slight narrowing we’ve seen in GB polls.
