Sir, – I read Adele Merson’s piece (NU August 28) on Alister Jack, the Scottish Secretary, indicating that another referendum on independence could be granted if desire for another one was demonstrated by a poll of 60% of the Scottish electorate. This was met with the predictable outraged response from Nicola Sturgeon and SNP MPs with cries that this denies the Scottish people the proper democratic right of another referendum. But of course, at the same time, this conveniently forgets two things. Firstly that Nicola Sturgeon and Alex Salmond signed the 2012 Edinburgh Agreement indicating the 2014 referendum would: “Deliver a fair test and a decisive expression of the views of people in Scotland and a result that everyone will respect”. Secondly that the SNP’s very own constitution states in section 27: “This constitution may not be changed, except by a vote of at least two-thirds (66%) of the delegates present and voting at National Conference.” More than a little whiff of dual standards and utter hypocrisy by SNP hierarchy, if I may say so!
