Support for a Yes vote on September 18 has been given a major boost following the Alex Salmond-Alistair Darling TV independence debate, fresh analysis of polling data has shown.
Crucially, undecided voters - who will play pivotal role in the outcome of the referendum – judged the First Minister to be the clear winner of the first televised contest.
And significantly the ICM poll taken for The Guardian immediately after the debate revealed a dramatic increase in support for Yes among women and older voters.
Overall, excluding 'don't knows', support for Yes increased by two per cent over the two-hour debate from 45% before the contest to 47% after.
Polling also shows that among undecided voters, Mr Salmond was seen as a clear winner – by 74% to 26%. For those who were undecided before the debate, the figures were 55% for the First Minister and 45% for Mr Darling.
Compared with the previous ICM poll - in July (for Scotland on Sunday) - support for Yes increased by nine percentage points to 42%, including undecided voters – the highest backing for Yes in any ICM poll since the 2011 Scottish Parliament election.
And when ‘Don’t Knows’ are factored out, support for Yes rises from 43% to 47% while No has slipped from 57% to 53% - a 4% swing to Yes.
Comparing last night’s ICM poll for The Guardian with the ICM poll in July, the biggest rise in support for Yes is among women – up by 9%. And the poll shows greater support for Yes among women (48%) than men (45%).
And compared to the previous ICM poll in July, the greatest increase in age-group support for Yes was among the over-55s - up by 9 points.
Commenting on the poll analysis, Yes Scotland Chief Executive Blair Jenkins said: "After a two-hour debate, support for Yes increased by two points to 47 per cent - a 4 point swing from the last ICM poll. We are winning decisively among undecided voters, and the debate generated big increases in support for Yes among women and older voters. We are winning where it matters, and I am extremely confident we will achieve the small swing now required to achieve a Yes majority on 18 September.
"The post-debate poll analysis shows that momentum remains with Yes - our optimistic and positive vision for a more prosperous and fairer Scotland is chiming with more and more people. It is particularly encouraging that as they weigh up the arguments, increasing numbers of women and older people are moving to Yes.
"This debate is about who is best placed and most trusted to make decisions about Scotland’s future – the people who live and work here and care most, or a Westminster system that is out of step and out of touch with the priorities and aspirations of people in Scotland. In a two-hour debate, Alistair Darling didn't have a single positive word to say.
"Support for Yes continues to grow because when people hear the arguments they realise that by seizing this unique opportunity to take our future into our own hands, we can turn that vision of a better and fairer Scotland into reality."
