Pressure for independence remains a major force in Scotland, but the case for it has changed substantially since the referendum of 2014. In the 2016 Brexit referendum, 60 per cent of the Scottish electorate voted to remain part of the European Union- the only part of the UK to reject Brexit so unequivocally.

This new analysis takes into account a host of economic issues including deficit, debt, currency, energy (including North Sea oil and gas), pensions, mortgages and the financial sector. It weighs up the advantages of rejoining the EU single market, either as a full EU member or as a member of the EEA, with the disadvantages of a hard border with the rest of the UK.

Independence would create opportunities, but it would also bring many thorny problems which the Scottish government, and the Scottish people, would have to face.
