A POLL has revealed that as many as one in five Scottish voters remain open-mined or undecided about Scottish independence.

A survey carried out for polling and research organisation Progress Scotland – fronted by former SNP depute leader Angus Robertson (pictured) – found 8% of respondents planned to vote the opposite way from 2014.

A further 13% said they don’t know how they will vote but that their views have changed since last time. Only 77% of the 2000 people polled said their views remained the same and they would vote the same way.

Robertson described the findings as “very encouraging given that 21%-strong group is significantly larger than the 5% difference that is required for the 2014 referendum to be overturned”.

The poll results come on top of those revealed by The National yesterday, which showed that Brexit has increased support for independence.

The Survation research found that 63% of undecided voters believe Brexit makes Scottish independence more likely, which 45% said Brexit has changed their view on independence.

Independent pollster Mark Diffley who set the questions for Progress Scotland explained the significance of the latest figures. He said: “Some traditional polls which ask a binary Yes/No choice suggest that the number of undecided voters is insignificant.

“But this research highlights that many more are actively thinking about their views on independence, with 21% of respondents having already either changed how they would vote compared to 2014 or whose views have changed a bit and are not sure how they would now vote in another referendum.

“We are trying to better understand the views of people who are open-minded or undecided about Scottish independence.

“We now look forward to doing further research to better understand these voters and their motivations. Results from our other polling questions make clear that Brexit is the biggest single current factor, but there are others, and we will be looking closely at better understanding them.”

Progress Scotland managing director Robertson, who analyses the poll findings in his column for The National today, said: “This research is hugely important to help understanding of undecided voters and those who are open-minded about Scottish independence.

“We have been able to commission this research through the generosity of thousands of people who are subscribing to Progress Scotland.

“Further supporters of this research can help fund future polls and focus groups with a small monthly subscription or donation via the Progress Scotland website: www.progressscotland.org.”

A total of 2041 people aged 16 or over and living in Scotland took part in the poll conducted for Progress Scotland by Survation between March 15 and 21, 2019.
