The story of Brexit in Scotland was about whether – and, if so, how – Scotland’s vote to Remain in the EU was to be acknowledged. In Albert Hirschman’s terminology, was it to be through the exercise of voice – a role for Scotland’s representatives in influencing the form of EU withdrawal and its domestic implications or through exit, by triggering a second independence referendum? In the end it was neither. The UK-wide majority to Leave the EU prevailed, with no concessions to the Scottish government’s preferred form of Brexit and no second independence referendum. This result exposed radically conflicting visions of the nature of the UK’s territorial constitution – a Union State based on Scottish popular sovereignty, or a Unitary State based on the sovereignty of the UK Parliament. A Brexit premised on the restoration of Parliamentary sovereignty and the desire to ‘take back control’ laid bare the subaltern nature of the Union-State account and the fragility of Scotland’s constitutional protections within the Union. Devolution in Scotland has been left diminished and the pathway towards independence mired in uncertainty.
