It’s the last Sunday before the referendum so we can expect several polls tonight (in fact, the chances are we’ll get lots today, and then comparatively few until Wednesday when there will be a glut of eve-of-referendum polls). I am expecting at least three today – Survation, Panelbase and Opinium – and I’ll update as they appear.

First out is Survation, conducted for the Better Together campaign. Their topline figures are YES 41%, NO 47%, Don’t know or refused 12%. Excluding the don’t knows and won’t says that works out at YES 46%, NO 54%. Full tables are here. I haven’t included any changes since last time as unlike all Survation’s previous Scottish referendum polls this one was conducted by telephone rather than online. It means we couldn’t confidently conclude anything from any change, though for what it’s worth it wouldn’t be showing any significant change anyway, Survation’s last online poll had YES 47%, NO 53%.

Later on we have an Opinium Scottish poll for the Observer, due at 8 o’clock, and a Panelbase for the Sunday Times.

UPDATE: The second Scottish poll of the evening is one we weren’t expecting – an ICM poll for the Sunday Telegraph here. The fieldwork was done at pretty much the same time as the telephone ICM poll for the Guardian yesterday, but this one was conducted online and has significantly different figures. Topline figures with changes from ICM’s last online poll are YES 49%(+11), NO 42%(-5), Don’t know 9%. Excluding don’t knows this works out at YES 54%(+9), NO 46%(-9). This echoes the large shift towards YES over the last month that YouGov and TNS have shown, but the significant lead for the YES campaign is in contrast to other polls, which are showing a small lead for the NO campaign.

Note that the sample size for the poll was only 705, smaller than usual but not obscenely so (a sample size of 705 increases the margin of error to 3.7%, so less precise than 1000, but not by a vast amount). Update with the Opinium poll coming up very soon….

UPDATE 2: The Opinium poll for the Observer is also out and has figures that are very much in line with the main pack – YES is on 45%, NO is on 49%, 6% say don’t know. Excluding don’t knows that works out at YES 47%, NO 53%. This is Opinium’s first outing in the Scottish referendum campaign, so no trend data. Full results are here, and Opinium have a note on methodology here – in Opinium’s usual GB polls they do not use any political weighting, but in their Scottish polling they are weighting by both 2011 recalled Holyrood vote AND recalled 2010 Westminster vote.

Still to come tonight we have at least a Panelbase poll for the Sunday Times.

UPDATE 3: What is presumably the final Scottish poll of the night is Panelbase for the Sunday Times, and has a wafer thin NO lead. Topline figures appear to be YES 49%(+1), NO 51%(-1) (they are being widely quoted at 49.4% to 50.6%, but quoting decimal places when you’ve a margin of error of plus or minus 3 whole percentage points always seems downright silly to me!). I’ll update again shortly with a roundup of where we stand.
