Latest voting intention polls
We've had three voting intention polls in the last couple of days:
- Ipsos MORI's monthly political monitor had topline figures of CON 43%(+4), LAB 42%(nc), LDEM 6%(-3). Fieldwork was over last weekend (Fri-Wed), and changes are from January. Tabs are here.
- YouGov/Times on Friday has toplines of CON 41%(nc), LAB 43%(+1), LDEM 7%(nc). Fieldwork was Mon-Tues and changes are from last week. Tabs are here.
- Survation/GMB, reported in the Sunday Mirror, has CON 37%(-3), LAB 44%(+1), LDEM 9%(+1). Fieldwork was Wednesday and Thursday, and changes are from the tail end of January. No tabs yet.
There is no clear trend - Labour is steady across the board, Survation have the Tories falling, MORI have them rising. MORI and YouGov show the two main parties neck-and-neck, Survation have a clear Labour lead.
The better Labour position in Survation is typical, but it's not really clear why. As regular readers will know, Survation do both online and telephone voting intention polls. Their phone polls really do have a significantly different methodology - rather than random digit dialling, they randomly select phone numbers from consumer databases and ring those specific people. That would be an obvious possible explanation for a difference between Survation phone polls and polls from other companies. However, this poll wasn't conducted by telephone, it was conducted online, and Survation's online method is pretty similar to everyone else's.
Survation's online samples at the general election were much the same as everyone elses. The differences were down to other companies experimenting with things like demographic turnout modelling in order to solve the problems of 2015, approaches that ultimately ended up backfiring. However, polling companies that got it wrong have now dropped the innovations that didn't work and largely gone back to simpler methods on turnout, meaning there is now no obvious reason for the difference.
Meanwhile, looking at the other questions in the surveys the YouGov poll also included their all their regular EU trackers, following Theresa May and Jeremy Corbyn's speeches. Neither, unsusprisingly, seem to have made much difference. 29% of people think that the Conservative party's policy on Brexit is clear, up on a week ago (25%) but still significantly down from January (37%). 36% of people say they support May's approach to Brexit, barely changed from a week ago (35%). For Labour, just 18% of people now think their Brexit policy is clear (down from 22% straight after Corbyn's speech), 21% of people say they support the approach that Jeremy Corbyn is taking towards Brexit.
