Today's Britain-wide YouGov poll is the first to have been entirely conducted since the BBC leaders' debate on Thursday night. There's a supplementary question about the debate itself, which shows that Nicola Sturgeon was judged to be the winner both by respondents across the whole of Britain, and by the Scottish subsample - although understandably her margin of victory was much, much bigger with the latter.
Which leader do you think came across best in the debate? (Respondents across Britain) :
Nicola Sturgeon 30%
Ed Miliband 27%
Nigel Farage 17%
Leanne Wood 3%
Natalie Bennett 3%
Which leader do you think came across best in the debate? (Respondents in Scotland only) :
Nicola Sturgeon 63%
Ed Miliband 22%
Nigel Farage 8%
Natalie Bennett 1%
Leanne Wood 0%
This isn't an instant poll, so respondents will have been influenced by the post-debate reporting, including the widespread reporting of the rather questionable instant poll from Survation that had Miliband slightly ahead (albeit only at Britain-wide level). So perhaps the most important thing about YouGov's result is the reassurance it provides us that the Survation poll didn't distort people's perception of the outcome - or at least not sufficiently to convince a plurality that Miliband won.
The headline voting intentions from YouGov's Scottish subsample are also of particular interest, as they're the first numbers we have that are entirely post-debate. They show : SNP 40%, Labour 27%, Conservatives 19%, UKIP 6%, Liberal Democrats 6%, Greens 2%. If that was the result of a full-scale poll, it would look like the gap had narrowed, but in subsample terms it's very much business as usual, and doesn't give rise to any obvious suspicion that the debate has changed the state of play.

Here's a damning verdict on the leader of Plaid Cymru from one member of the YouGov panel -
"Uniformed spreader of misinformation, stupidly taken in by Nicola Sturgeon."
Hmmm. Let's be fair to Leanne - she may be a gullible spreader of misinformation, but at least she has the common decency to do it in a uniform.
