More from Sunday's YouGov poll

The full tables for the Yougov/Sunday Times poll are now up on YouGov's website. I'll start with the standard leaders approval ratings - which we can compared to those in the last YouGov Sunday Times poll just before conference season - Cameron's approval rating is virtually unchanged, from +28 to +27, Brown's is slightly up from -44 to -39, Clegg is slightly down from +17 to +13.

Moving on the more varied topics, as usual the Sunday Times asked topics on a range of issues. Asked about whether MPs should be made to pay back expenses that Sir Thomas Legg has ruled are unreasonable, even if they were within the rules at the time, 65% of YouGov's respondents thought they should, with 28% thinking that retrospective rule changes are wrong. 69% also thought David Cameron was right to say Tory MPs who do not pay up will not be allowed to stand as Conservatives at the next election.

38% of people agreed there should be an immediate election to "purge" Parliament of MPs who abused the expenses system, 53% disagreed. I expect even these answers are more about partisan opinions of the government than expenses - 63% of Tory voters think there need to be an election, 84% of Labour voters think there shouldn't.

YouGov also asked if people might consider voting for a minor party or abstaining over the expenses issue. I don't like questions like this, since it is psychologically a lot easier to say in a survey that you might switch than it is to actually do it, and the question sets very low thresholds indeed ("might consider switching"). However, the party splits are interesting - amongst Conservative and Labour voters 7% say they would definitely consider switching to a minor party or abstaining, but amongst Lib Dem voters it is 12%.

As I mentioned yesterday, YouGov also asked if the BBC was right to invite Nick Griffin onto Question Time. 63% agreed with the statement "The BBC was RIGHT to invite him, as the BNP has two members of the European Parliament", 23% that "The BBC was WRONG to give him, as it should not provide a platform for someone with such extreme and objectionable views".

There were also some questions on the Lisbon Treaty. Voting intention in a referendum on the treaty stands at 18% YES, 41% NO and 41% don't know or wouldn't vote. Opinion on Tony Blair's candidancy as President of the European Union remains split, 38% support to 38% opposed.

While I'm on the issue of Sunday polls, the Mail on Sunday also claimed to have a poll conducted in Redditch asking about Jacqui Smith. As fas as I can tell it was conducted by 3 Mail on Sunday journalists going up there with clipboards, so I'd be gobsmacked if there was any attempt at representative sampling or weighting. Ignore (if you weren't already).

I haven't had any confirmation, but on normal timings we should be getting ICM in the Guardian today or tomorrow.
