The Queen has urged Scottish voters to "think very carefully" before casting their ballots in Thursday's referendum.
She was heard making the off-camera remarks to members of the public during a visit to Crathie Church in Aberdeenshire.
The Telegraph newspaper said it understood the monarch had told the small crowd:
You have an important vote on Thursday.
I hope everybody thinks very carefully about the referendum this week.
It is thought to be her first public comment on the issue of Scottish independence.
One story dominates Thursday's front pages with some newspapers printing emotive pleas to voters to keep the United Kingdom as one.
In Edinburgh tonight you can hear it and feel it. The buzz, the banter of the day and the thrilling sense something big is coming tomorrow.
There is nervousness, anxiety and on the streets of Edinburgh fuelled by an atmosphere unlike anything seen before in recent UK politics.
