New ICM, Populus and YouGov polls
We could have several polls tonight, given most of last month's polls ended up being conducted over the same weekend. The first one out is ICM's monthly poll for the Guardian. Last month's Guardian poll had shown a Tory lead of five points, this month it slips back to a rather more typical figure - CON 36%(-4), LAB 37%(+2), LDEM 14%(-2), Others 13%(+4). Certainly that others figures looks like something of a reversion to the mean - 9% really was unusually low.
There is also an interesting question on trust in the NHS, repeated from 2006 early in David Cameron's leadership. Back then 14% said they trusted the Tories a lot on the NHS, 47% trusted them a little and 31% didn't trust them at all. The figures now at 13% who trust the Tories a lot (down 1), 42% who trust them a little (down 5), 40% do not trust them at all (up 9). This suggests a drop in the proportion of people who trust the Tories a little on the NHS, though the hardcore of people who trusted them a lot was minimal to begin with.
On the same question for Labour 23% trust them a lot(up 4), 46% trust them a little (up 2), 25% do not trust them at all (down 7).
We've certainly got the daily YouGov poll for the Sun to come tonight, I don't know if Populus and Ipsos MORI's monthly polls will also turn up today or tomorrow, or whether they'll be done next weekend.
UPDATE: The monthly Populus poll for the Times has now been released, topline figures are CON 37%(nc), LAB 39%(+1), LDEM 11%(-2). Putting aside the usual variation we get between different companies Liberal Democrat scores we are actually getting quite a consistent picture on the Con vs Lab horse race - YouGov's daily polls have been averaging a Labour lead of about 1.5 points, ICM tonight are showing a 1 point Labour lead and the Populus are showing a 2 point Labour lead.
UPDATE2: And finally (assuming MORI don't pop out of the woodwork), the Sun politics team have tweeted the YouGov figures for tonight. Topline figures are CON 39%, LAB 38%, LDEM 10%, so while the lead is bouncing back and forth (much as we'd expect from normal variation within the margin of error), it's still very much in line with YouGov's average position of a small Labour lead (and the 7 point figure for the Lib Dems yesterday does appear to have been an outlier).
