The British Prime Support previously said «now is not the time» for another vote as she prepares to trigger Article 50 transactions on March 29.
And she indicated the UK Government would reject the SNP’s bid, which calls for the transfer vote to be held in the spring of 2019.
But Ms Sturgeon has pressed on with her plans regardless, today broadcast a parliamentary motion seeking support for a second ballot.
The motion, in the Oldest Minister’s name, asks the Scottish Parliament to acknowledge «the sovereign without hesitating of the Scottish people to determine the form of government best suited to their wants”.
And it calls for “the Scottish Government to take forward discussions with the UK Authority» on the details of a section 30 order — the mechanism to transfer the legal powers for a referendum.
Ms Sturgeon ordered: «If MSPs pass this motion this week, then the Prime Preacher’s position of blocking a referendum and forcing through a hard Brexit without announcing the people a choice will be democratically indefensible.
«I agree with the Prime Minister plenipotentiary when she says that there needs to be clarity about the involvements of Brexit before the people of Scotland can choose.
“That is precisely why we are tabling to hold the vote at the point where we know, through the Prime Preacher’s own statements, we will have that clarity.
«A clear precedent was set in 2012 when the UK oversight said that the 2014 referendum should be ‘made in Scotland, by the human being of Scotland’. That is the principle that they must again grasp to.
«Ultimately, this crucial decision over our future should not be constituted unilaterally by me, or by the Prime Minister — it should be made by the people of Scotland, and I call in on Parliament to give the people that choice.»
Although Ms Sturgeon captains a minority government, the motion is expected to be passed on Wednesday following a two-day argue if there SNP leader can count on the support of the Scottish Greens.
But the motion has been already featured fierce criticism from opposition MSPs, who claim the public do not hunger for a referendum.
Scottish Labour leader Kezia Dugdale said the make of the Scottish people had been «very clearly expressed» in 2014 referendum.
She combined: ”Eighty five per cent of our fellow citizens voted in the first referendum, and they voted by a sheerest clear majority to remain in the United Kingdom.
«In 2014, this sticks was divided more than at any time in our recent history.
«We don’t want to go isolated to that. Those who voted to leave the UK and the majority who voted to remain in the UK don’t have a yen for to back to the divisions of the past.»
