Ipsos MORI’s monthly political monitor is out in today’s Evening Standard with topline figures of CON 32%(+2), LAB 29%(-4), LDEM 9%(+1), UKIP 14%(-2), GRN 7%. The three point Conservative lead is the highest that MORI have shown since 2010 and the highest that any company has shown since January 2012. Full details are here.

As usual it’s the unusual poll that gets the attention, when it should be the trend. The fieldwork for the poll was conducted between Saturday and Monday when the media was full of stories about Labour having a leadership crisis, so naturally enough people have concluded that Labour’s leadership row has damaged them in the polls.

Except the MORI poll wasn’t the only poll conducted at the weekend. ICM also had a poll in the field at the same time, which showed Labour one point ahead (though down three on the previous month). Lord Ashcroft also had a poll conducted at the weekend, which showed a one point Conservative lead, but no change from the previous week. Populus had a poll conducted over the weekend too – it showed Labour holding on to a two point lead. YouGov had a poll conducted Sunday to Monday and another one since then, both showed a one point Labour lead, unchanged from last week.

The fact that this is the largest Conservative lead and the lowest Labour score for years is meaningful in its own way. It’s reflection of a general trend that has shown Labour drop from an average lead of around six points at the start of year, to an average lead of around about one point now. What the six polls we’ve had since the weekend don’t agree on is that last weekend’s row over Miliband’s leadership had any huge impact on this pre-existing trend.

There has been comparatively little Scottish polling since the referendum (partly I expect because newspapers had spent their budgets on pre-referendum polling). I’ve seen some people spending rather too much time collating and looking at Scottish crossbreaks in GB polls. Personally I wouldn’t recommend putting too much weight on crossbreaks – aggregating them up gets round the sample size issue, but GB polls are still weighted at the GB level. If you think back to how het up people got about whether Scottish polls were weighted by Holyrood or Westminster voting intention, factored in place of birth, things like that – the Scottish sub-sample in a GB poll have no such controls, it’s just how the Scottish respondents in a poll weighted to GB targets happen to fall out.

Nevertheless, they are a straw in the wind, and they’d been suggesting a strong showing for the SNP since the referendum. Today we have a proper, bespoke Scottish poll by Ipsos MORI and if anything it shows the SNP doing even better than the crossbreaks suggested. Topline voting intentions in Westminster with changes since the general election are CON 10%(-7), LAB 23%(-19), LDEM 6%(-13), SNP 52%(+32), GRN 6%(+5). Full results are here

This would, to say the least, be rather a radical turnaround from the last general election. I don’t think swingometers offer much guidance in the case of really extreme results (a uniform swing would be mathematically impossible on this results – for example, there are about 9 seats in Scotland where Labour got less than 19% in 2010, so couldn’t lose 19% this time round. The same applies in many seats for the Liberal Democrats) but for the record on a uniform swing these figures would result in the SNP winning all but two seats in Scotland.

Ipsos MORI’s monthly political monitor is out in today’s Standard. Topline figures are CON 30%(-4), LAB 33%(nc), LDEM 8%(+1), UKIP 16%(+1). The 16% for UKIP is up only one since last month, but that makes it the highest UKIP score MORI have yet recorded. There was a similar pattern in this morning’s YouGov poll for the Sun – topline figures were CON 30%, LAB 34%, LDEM 8%, UKIP 18%, beating YouGov’s previous UKIP high of 17 (Tabs are here: MORI, YouGov)

The very last pre-election poll of the referendum campaign is by Ipsos MORI, for the Standard, and has topline figures of YES 47%, NO 53%. Once again, it is bang in line with all other other companies, who to a man (or woman) have YES between 47%-49%, NO between 51-53%. Full result for the MORI poll will, in due course, be here.

Ipsos MORI still have a final final poll to come in tomorrow’s Evening Standard, but they also have a Scottish poll out tonight for STV. Topline voting intention figures with changes from their previous Scottish poll, right back at the start of August, are YES 49%(+7), NO 51%(-7). As with the YouGov, TNS and ICM polls they’ve shown a big shift towards YES over the last month and, as with everyone else, they end the campaign with YES and NO extremely close, but NO just an inch ahead. I’ll add tables later on…
