The SNP leader said she will make her long-awaited statement an a second referendum when the current "chaotic" negotiations are concluded. With an extension to Brexit likely, that may take months.
But Ms Sturgeon made it clear today that she will be pressing ahead with plans for a second vote.
"When we get to the end of this chaotic phase of negotiations, which I hope is very soon, then I will set out how I intend to exercise that mandate."
The SNP leader's position will lead to an impasse with Westminster which has power over the constitution. Theresa May has indicated that she would refuse Holyrood authority over such a move.
"Scotland has been ignored," Ms Sturgeon added.
"Our vote to remain has been ignored, every attempt at compromise has been ignored.
"Yesterday we had the absurd situation where a handful of DUP MPs had more sway over the future of Scotland than our national parliament did.
"And of course, there's the long-term consequences of Brexit if it happens.
"My priority as First Minister is to protect Scotland as much as possible."
