Days before the vote, with the opinion polls closing, the three Better Together party leaders issued 'The Vow', a promise of more powers for Scotland in the event of a No vote. The referendum resulted in Scotland voting by 55% to 45% to remain part of the United Kingdom. First minister Alex Salmond resigned shortly after the defeat, succeeded by Nicola Sturgeon.
