Just as Nigel Farage said before the Brexit referendum that "a 52% win for Remain would be unfinished business by a long way", yet the Brexiteers regard a 52% win for Leave as a permanent decision and never to be revisited, and from 1975 until Cameron called the 2016 referendum pro-EU politicians complacently believed that the 1975 referendum had settled the matter once and for all and that no government would ever want to revisit the issue.I wonder if Ms Sturgeon and her successors will subscribe to that idea if or when Scotland votes for independence? My feeling is that the SNP regards "no" to independence as a temporary decision, but will regard "yes" as permanent and never to be questioned again.
