PROGRESS Scotland conducted a series of interviews with former No voters who are either questioning or have changed their views since 2014. You can see videos of these at www.progressscotland.org but here is what some of them have to say.

Sir David Edward, the former UK judge on the European Court of Justice, explains how his views have been changing: "In 2014, I was a committed ‘No’ voter - head and heart. I’m now not so sure. I’m ambivalent.

“It seems to me that we may have to choose on the one hand between the undoubted uncertainties of independence and on the other exit from the EU, and being ruled by people in London who don’t understand or believe in the constitutional implications of the devolution settlement.  And if that’s the choice, I could be persuaded to vote for independence. 

“To be persuaded to vote for independence, I would need to see much more evidence that Scotland and its institutions are capable of bearing the intellectual, financial and administrative burdens that independence would involve”.

Caroline Castle, an Edinburgh-based businesswoman who is originally from England, says: “I teach English to EU and other foreign national citizens in Edinburgh. I voted No in 2014 because I didn’t think it was in Scotland’s best interests to break away from the UK and lose its membership of the EU. I didn’t anticipate what would happen two years later.

“Brexit is already a catastrophe , creating division, damaging our reputation and economy. If the UK Government continues on its present course this will only get worse. So many people in England are in despair because they don’t have any choice as both Labour and the Tories are committed to Brexit.

“Scotland does have a choice and unless the UK Government compromises or there is a People’s Vote that reverses Brexit, I would now vote for independence. We know that referendums cause division, so I think the timing of a referendum on independence should be when there is a clear majority of voters wanting it.”

The solicitor advocate Mike Dailly who was previously a Labour Party activist and Better Together supporter said: “For me it has been a gradual realisation over time that Scotland’s future will only be achieved through independence. In 2014 in Scotland we said that if you voted No, that would guarantee our right to remain in the EU. Now that has proven to be false. We had 62% of people in Scotland wanting to stay in the EU. We are being dragged out of Europe, possibly with a hard Brexit which will cause untold misery and detriment to people and businesses in Scotland. So for me there are a number of reasons why I’ve ultimately come to the conclusion that Scotland’s ambition will only be achieved if we have self-determination.”

The Edinburgh councillor Ashley Graczyk, who was elected as a Tory but now sits as an independent, said: “Disability rights really matter to me as someone who is profoundly deaf and I have had growing concerns about how the vulnerable are treated by Westminster. In 2014 I voted No because I thought the status quo was safe. But things have changed massively. Between the treatment of the vulnerable people with disabilities and the treatment of Scotland, which didn’t vote for Brexit, I decided to declare my support for Scottish independence and will definitely be voting Yes at the next referendum.”

Politics student and young LibDem member Chris Wilson, from Lanarkshire, says: “As a proud LibDem, Scot and European, I believe we must respect the EU referendum result in Scotland. The EU empowers young people like myself with the Erasmus Scheme, while advocating civil liberties and basic human rights. LibDems like me will have to make a choice sooner or later about which Union we prefer. I choose for Scotland to set its own path as a progressive, socially democratic society within the European Union, not as part of an increasingly right-wing intolerant United Kingdom.”

Youth activist Erin Mwembo, from East Lothian, says: “I was too young to vote in 2014 but would probably have voted No. My views have changed and, like most young people in Scotland, I now support independence. Being responsible for our own future and making better decisions closer to home is definitely the best future for Scotland and everyone who lives here. Looking at the Brexit mess at Westminster I’m convinced we can do better. Many people like me have been changing their views on independence and I think many more will do the same.”
