A second referendum on the independence of Scotland from the United Kingdom (UK) has been proposed by the Scottish Government. An independence referendum was first held on 18 September 2014, with 55% voting "No" to independence. The Scottish Government stated in its white paper for independence that voting Yes was a "once in a generation opportunity to follow a different path, and choose a new and better direction for our nation". Following the "No" vote, the cross party Smith Commission proposed areas that could be devolved to the Scottish Parliament; this led to the passing of the Scotland Act 2016, formalising new devolved policy areas in time for the 2016 Scottish Parliament election campaign.

Scottish independence is the idea of Scotland regaining its independence and once again becoming a sovereign state, independent from the United Kingdom. The term Scottish independence refers to the political movement that is campaigning to bring it about.
