Nicola Sturgeon has hailed a new 'reverse Greenland' proposal which could potentially allow England and Wales to withdraw from the EU and allow Scotland to remain a member.
Denmark-based academic Ulrik Pram Gad has suggested that the UK could look at Greenland's exit from the EU while the rest of the Kingdom of Denmark remained.
England and Wales, which voted to leave, could seek territorial exemption from the continuing UK member state, allowing Scotland, Northern Ireland and Gibraltar - all of whom voted to stay - to remain in the European bloc.
Mr Gad made this suggestion in an article for the London School of Economics, which Ms Sturgeon tweeted a link to, saying: "Interesting piece by a Denmark based academic - Could a 'reverse Greenland' arrangement keep Scotland in the EU?"
Mr Gad said in his article that this arrangement "might solve" the issue for the three regions which want to stay, but still leaves the problem of England and Wales' relationship with the EU and the single market.
