The Scotsman have published further details from their ICM poll, and there must be a fair chance that this will be the final full-scale poll of Scottish voting intentions for the European Parliament prior to the election on Thursday.
SNP 36% (-1)
Labour 27% (-1)
Conservatives 13% (+2)
UKIP 9% (-1)
Liberal Democrats 7% (n/c)
Greens 7% (+3)
That would translate into three seats for the SNP, two for Labour and one for the Tories - effectively meaning that the Lib Dems would lose their only seat to the SNP, who currently have two. Under this scenario, it would be the SNP who take the last of the six seats and thus perform the almost mythically heroic role of "the party that stopped UKIP". There are other scenarios in which it might be Labour or the Tories who assume that role, but barring something miraculous it won't be the Greens or the Lib Dems. So a "tactical vote" for the Greens in the hope of stopping UKIP still looks utterly counter-productive.
In any case, the number one priority for any SNP supporter must surely be to ensure the SNP win the popular vote, because failure to do so might drain momentum away from the pro-independence campaign at a critical stage. The party may look assured of top place on these numbers, but that could yet prove deceptive - YouGov are showing a much less clear-cut position, and previous European elections have often confounded predictions due to very low turnouts.
It's fascinating that the SNP's vote is virtually identical to last month's in spite of the change in referendum voting intentions. There are two ways of looking at that - on the one hand it means that we can't put the referendum figures down to there being too few SNP supporters in the sample, but on the other hand it underlines that the referendum race is becoming increasingly decoupled from regular voting intention. That suggests there's no automatic reason to be suspicious of a Yes-friendly referendum poll just because the SNP are doing particularly well in supplementary questions. That said, it would still be a cause for some concern if the SNP's performance on Thursday doesn't live up to the forecasts of the broadly Yes-friendly pollsters.
