Salmond v Darling debate

Tonight is the long awaited Scottish debate between Alex Salmond and Alistair Darling. STV released their latest Ipsos MORI at the start of the debate - topline figures there are YES 40%(+4), NO 54%(nc), don't knows just 6%. Excluding don't knows that works out at YES 42%(+2), NO 58%(-2).

MORI tend to be one of those pollsters who show more favourable figures for the NO campaign, so by their standards its a favourable poll for YES. Then again, if MORI are right, then a sixteen point lead for NO is still a a big gap to close with only six weeks to go.

Following the debate the only instant poll I'm aware of is ICM for the Guardian, due to go out about 9.40 (results will hopefully be before ten, but it obviously depends on how quickly people respond!)

UPDATE: ICM's instant poll crowns Darling the winner - 56% for Darling, 44% for Alex Salmond. The figures are, incidentally, very close to the sort of NO/YES figures ICM report in referendum voting intentions. We'll know properly when we see ICM's tables, but I suspect we may find that people who were voting YES anyway thought Salmond won, people who were voting NO anyway thought Darling won.

UPDATE2: Full figures including don't knows were Darling 47%, Salmond 37%, Don't Know 15%. Sample size was 512.

UPDATE3: Tabs are here. People's perceptions of who won were, as suspected, largely in line with their pre-existing dispositions towards independence, though not entirely. Amongst people who were voting NO before the debate people thought Darling won by 83% to 6%. Amongst pre-debate YES voters people thought Salmond won by 72% to 16%. Amongst people who said they were don't knows, Salmond was slightly ahead - 44% to 36% (albeit, there were only 63 don't knows, so we're talking about the difference of 4 or 5 people). Bottom line is that there was no big knockout blow here - the large majority of both sides thought their own "champion" won, don't knows were pretty evenly split.
