I'd heard that Alistair Carmichael made a questionable comment about the recent TNS-BMRB poll on today's edition of the Sunday Politics, but until I watched the interview on iplayer a few minutes ago I didn't realise that the comment contained a flat-out untruth -
"Yes, there was a couple of polls last week that said that the gap was narrowing a bit, but in fact the most recent poll of all, the poll on Wednesday from TNS...showed that only 28% of people in Scotland were prepared to say that they were voting Yes, as opposed to the 42% who were on our side of the argument."
OK, here are the facts -
1) The TNS poll was published on Tuesday, not Wednesday.
2) The fieldwork for the TNS poll entirely predated two of the four recent polls that showed the gap narrowing, and partially predated the other two.
3) Even the publication of the TNS poll preceded the publication of Wednesday's YouGov poll by 24 hours.
So I'm afraid there is no get-out clause for Carmichael here - it is simply not possible for him to truthfully claim that the TNS poll is "the most recent one of all". By any definition, the most recent poll that we know of at present is the landmark YouGov poll that showed the Yes vote rising from 40% to 42%.
