Scottish Liberal Democrat leader Willie Rennie has challenged Nicola Sturgeon to abandon her accelerated pathway to another referendum which she announced at the BBC Leaders Debate in Aberdeen.
Mr Rennie has warned that the uncertainty would have a damaging impact on the economic recovery.
It would mean that the SNP have gone back on their commitment that there would be no new independence referendum for a lifetime.
Mr Rennie said:
"We're heading towards Neverendums until the SNP get the answer they want from the voters.
"Not even a year has passed since the referendum and the SNP have gone back on their word. The once in a lifetime promise has been dispensed in favour of an accelerated pathway to another referendum.
"Their policy means that they will be able to drag the country to yet another referendum whenever they fancy. They just have to think up a reason and then order their MSPs to vote it through.
“Those MSPs were elected on a minority of votes across Scotland but will be given total power.
“Public services such as Scotland’s NHS would be neglected as they sought to find a reason to meet Nicola Sturgeon’s accelerated pathway.
"Nicola Sturgeon must scrap her plan for an accelerated pathway to another referendum.
"This new promise is for neverending uncertainty and a neverendum.
"We have seen from Canada the economic impact of an uncertain constitutional environment. Quebec lost jobs and wealth. That damaged the province in the long term. The uncertainty alone could threaten the recovery.”
