It shows you how much the calling of a snap general election changes our priorities, but we've just had two new polls in which the question about independence has been treated as an afterthought. Let's put that right, because the findings make for moderately pleasant reading. Here are the Survation numbers...
Should Scotland be an independent country? (Survation)
Yes 46.9% (+0.1)
No 53.1% (-0.1)
A 0.1% swing in favour of Yes is obviously not remotely significant, but here's the thing - this poll is not directly comparable with the last Survation poll, because 16 and 17 year olds were excluded this time. There's a semi-reasonable excuse for that, because the independence question was a supplementary in a poll that was primarily interested in voting intentions for an election from which under-18s will be excluded. But it does mean there are reasonable grounds for suspecting that the increase in the Yes vote might otherwise be a tad bigger. At the very least, there doesn't seem to have been any recent slippage in support for independence.
The Panelbase datasets aren't out yet, but it appears that 16 and 17 year olds were also excluded from that poll. In spite of that in-built handicap, Yes manages a small increase.
Should Scotland be an independent country? (Panelbase)
Yes 45% (+1)
No 55% (-1)
Basically the Survation numbers are par for the course, and the Panelbase numbers perhaps remain a little below par - but in combination the two polls give the lie to any notion that support for independence is consistently slipping below the 45% achieved in the 2014 referendum. For what it's worth, it remains the case that the only published telephone poll of the year so far actually gave Yes a very slight outright lead.

I'm still not sure how the Greens fared in the Panelbase poll, but we're not going to get an answer from Survation, who seemingly just lumped the Greens in with UKIP and others in a general "some other party" category. That said, including the Greens can also produce a distorted outcome, because people might indicate that they are planning to vote Green when there isn't even a Green candidate in their own constituency.

Scottish subsamples of GB-wide polls are obviously much less meaningful than full-scale Scottish polls. Nevertheless, the first inkling we had of the Scottish Tory surge over the last few days came from subsamples, which makes it interesting that the two most recent subsamples we have right now are somewhat less favourable for the Tories. Both are based on fieldwork that is slightly more up-to-date than the two full-scale polls from Survation and Panelbase. Today's YouGov subsample has the SNP on 49% and the Tories on 27%, while the subsample from today's Britain-wide Survation poll has the SNP on 45% and the Tories on only 19% (behind even Labour).
