Andrew Marr discovers why the Scotland he was born in has changed so much politically. Andrew looks back at the historic Scottish Independence Referendum of 2014. Why did support for pro-independence Yes Scotland rise from 28% to 45%? How did unionist Better Together eventually persuade a majority to vote no? Now Andrew discovers how the independence referendum has transformed Scottish politics. In the EU referendum in June 2016, every single local authority area in Scotland voted to remain. Politics in Scotland is moving apart from Britain - but this doesn't make the result of a second independence referendum a foregone conclusion.
