Britain’s top court is due to begin hearing arguments on Tuesday on whether Scotland’s semi-autonomous administration can organise an independence vote without the London government’s consent.
Scottish First Minister Nicola Sturgeon plans to hold a new independence referendum in October next year, but the UK government is adamant it won't happen, saying the 2014 referendum -- which was won by the 'no' campaign with 55% of the vote to 44% in favour of independence -- was a 'once in a generation event.'
Since then the numbers have tightened and Scots are evenly split on independence, although they have consistently returned pro-independence politicians to parliaments in Westminster and Edinburgh over the last eight years, with the SNP winning every national vote since then.
The Scottish Parliament currently has a majority of MSPs who are pro-independence from Sturgeon's Scottish National Party and the Greens.
Five judges on the UK's Supreme Court in London will hear arguments in this case over the next two days, although a decision is not expected for weeks, or possibly even months.
