The intention to hold a second referendum was in the SNP’s 2021 manifesto.

In 2021 the SNP and Green parties combined formed a government which had a majority in Holyrood. It is true that more people voted for the unionist parties, but only by a ba hair. In 2014 there was a majority of just under 385,000 for the union. In 2021 38,540 more people voted for the unionist parties than for the pro indy parties. Less than the average attendance at Ibrox. In my opinion the matter is not settled and it won’t be settled by the parties and their supporters staying in their silos and trotting out their party pieces about one another. There is an urgent need for all sides to work together for all of Scotland right now Unionists should accept that people should be able to campaign for indy and that there should be a legal route to independence. Indy supporters must accept that unionists are just as Scottish as they are.
