The UK's top court is set to hear arguments on whether Scotland can call another independence referendum without the consent of the Westminster government.
Nicola Sturgeon wants to hold another vote on Scotland's future on October 19, 2023, but the UK Government has refused permission which led to the First Minister asking the Supreme Court in London to rule if she can hold one without Liz Truss's say.
Five judges - Lord Reed, Lord Lloyd-Jones, Lord Sales, Lord Stephens and Lady Rose - will hear arguments from both sides over the next two days with an outcome expected later this year.
Ahead of the case the Daily Record has looked back at every independence opinion poll from the last year to see how both sides are doing in the debate.
Since October 27 last year there have been 23 opinion polls conducted by a number of outlets with the independence side leading in just three surveys.
Here's what the polls have said over the last year:
October 2022
October 4: Ahead of the SNP conference in Aberdeen two opinion polls gave the 'No' side a very narrow lead. A Savanta ComRes survey for the Scotsman where 1,029 people were asked about if Scotland should become an independent country found that 46 per cent said 'No' with 45 per cent answering 'Yes'.
Another poll of 1,067 people for The Times by YouGov on the same day gave the remain side a two per cent lead.
September 2022
September 16: A Deltapoll/Sun on Sunday poll gave the remain side a five per cent lead with 47 per cent saying 'No' with 42 per cent opting for the 'Yes' option.
Seven per cent of the 659 people surveyed said they did not know how they would vote if asked about Scottish independence.
August 2022
