SNP calls for a second independence referendum in the wake of the Brexit result are "completely irresponsible" and "utterly unjustified", according to the Scottish Conservative leader.
Ruth Davidson is expected to challenge Nicola Sturgeon's party on Tuesday and ask to "put the national interest before its own nationalist vision for once."
Ms Sturgeon, the SNP leader and First Minister, has already said a second referendum on Scottish independence is "highly likely".
Ms Davidson will insist the memories of "divisiveness and toxicity" of the 2014 referendum campaign means that most Scots do not currently support staging another vote on the issue.
She will say: "The SNP is, as usual, trying to seize on a moment of doubt and uncertainty to declare that the shining star of independence is the answer.
"And it's trying to claim that, as a result of Brexit, there is now a massive groundswell for a second independence referendum.
"This is simply not true. Even after the EU vote, only four in 10 people in Scotland say there should be an independence referendum.
"You cannot uphold the EU referendum result in Scotland as sacrosanct while trashing the Independence referendum vote we held just 22 months ago.
"And you don't solve the questions around leaving one union by walking out on an even more important one."
