The Survation poll, conducted in the wake of last week’s EU referendum, suggests some No voters have changed their minds following the UK’s decision to leave the European Union.
The survey for the Daily Mail found 47 per cent would vote Yes in a second independence referendum, with 41 per cent for No and 12 per cent undecided.
When the “don’t knows” are stripped out, 53 per cent back Yes and 47 per cent back No.
It is one of several polls conducted after the EU ballot showing majority support for independence.
Leave won 52 per cent of the vote in last week’s EU referendum, although 62 per cent of Scottish voters backed Remain.
First Minister Nicola Sturgeon has vowed to explore every option to protect Scotland’s place in the EU, stating a second independence ballot will be put forward by the Scottish Government if it emerges as the “best or only” way of achieving this.
Survation quizzed 1,055 adults between June 24 and June 28.
The poll also revealed that 35 per cent of SNP voters backed the Leave campaign, 47 per cent want a second independence referendum and 52 per cent agree with Ms Sturgeon it would be “democratically unacceptable” for Scotland to leave the EU.
An online poll, carried out in the aftermath of the EU vote, had support for Scottish independence at 59 per cent based on the question “If there was a referendum tomorrow with the question ‘Should Scotland be an independence country?’ how would you vote?”
