First Minister Nicola Sturgeon is to launch a fresh campaign for Scottish independence, with the first in a series of economic papers due today.
In a BBC Scotland interview, she said she still planned to hold another vote before the end of next year.
Asked whether she was now formally beginning the campaign for indyref2, the first minister replied: "Yes".
Ms Sturgeon said she would unveil the first in a series of new papers setting out the case for independence later this morning.
She added: "Had we known in 2014 everything we know now about the path the UK would have taken then, I've got no doubt Scotland would have voted yes back then."
The first referendum on Scottish independence took place on 18 September 2014 when 55% of voters said "No" to the change while 45% said "Yes".
The first paper on the new independence push - entitled 'Wealthier, Happier, Fairer: Why Not Scotland?' - will be a "scene setter" which will compare Scotland and the UK to other European countries and set out why the government believes the country would be better off if it were independent.
Ms Sturgeon added that subsequent papers would look at a number of areas including;
- currency
- tax and spend
- defence
- social security and pensions
- and EU membership and trade
The first minister told the BBC: "The conclusion very clearly is that Scotland could be doing much better as an independent country... Nobody right now can look at the UK - the mess it's in currently and its prospects for the UK outside of the European Union surely and conclude anything other than that Scotland can do better as an independent country."
In response to the new campaign for a referendum, the Scottish Conservatives' Donald Cameron said the vast majority did not want the "distraction" of another referendum next year.
He said the public wanted 100% of the government's focus to be on Covid recovery, the cost-of-living crisis, and supporting the health service.
Sarah Boyack, of Scottish Labour, said the government's attention was "still on their constitutional obsession".
She said it was an "appalling waste of time, energy and money" and that independence would "make Brexit look like a walk in the park".
Alex Cole-Hamilton, the Scottish Lib Dem leader, said the Scottish government cared "more about their independence obsession than everyone stuck on the longest NHS waiting lists in history, the cost of living crisis or the climate emergency.
"Nobody believes education is Nicola Sturgeon's top priority any more.
