First Minister Nicola Sturgeon is to launch a fresh campaign for Scottish independence.
Asked whether she was now formally beginning the campaign for indyref2, the first minister replied: "Yes".
She also insisted she still planned to hold another vote before the end of next year.
Ms Sturgeon said she would unveil the first in a series of new papers setting out the case for independence on Tuesday.
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".
Supporters of the Union have accused the Scottish government of being obsessed with independence.
