Nicola Sturgeon has unveiled her plan for another referendum on Scottish independence. The plebiscite – which Westminster will have to legislate for – will use the same question as in 2014 (‘Should Scotland be an independent country?’), and take place on 19 October 2023. The Lord Advocate, one of Sturgeon’s ministers, has referred the provisions of the Bill to the Supreme Court to determine whether they are in line with devolved powers.
