Yes, some people (including some politicians) described the EU referendum as “nothing more than a glorified opinion poll”. We have seen that it was no such thing.
However, this is somewhat different. Constitutional matters concerning the United Kingdom is not in the Scottish Parliament’s remit. They are reserved for Westminster. There is nothing to stop the Scottish “government” organising a referendum on the matter but, without the Westminster Parliament’s approval it truly would be a glorified opinion poll. The UK Parliament has the wellbeing of the entire UK to consider. The coming two years will be difficult which will see considerable amounts of Minsters’ and Civil Servants’ time being consumed with Brexit. A Scottish referendum will clearly impinge upon those resources. Mrs May is wise to refuse to accede to this diversion.
Ms Sturgeon makes great play of the fact that Brexit may have changed Scottish public opinion. She may be right, who knows? But she should remember that in 2014, when the first vote was held, the UK government had already promised a referendum on EU membership. She should also bear in mind that 40% of Scots voted to remain in the EU. Those Scots concerned that they would be taken out of the EU “against their will” (of which there was always a chance) should have voted for independence then. But insufficient numbers of them did. Quite how it would have altered the situation for the Scots anyway is a little unclear. Even if they had achieved independence by now, they would not be EU members. They would have lost their EU membership as part of the UK when they broke away and there is absolutely no chance of them being accepted as an independent nation in the short term and I would say it is unlikely in the medium to long term either.
Ms Sturgeon is described as a “canny” politician. Let’s see: she is quite prepared to see Scotland quit the UK, pledging instead a relationship with the EU which is all but certain to be based on a false promise. But as a result she will see Scotland quit the single market that is the UK, where far and away the greatest share of their trade is undertaken. So canny is not the word I’d use.
The ridiculous devolution nonsense put in place by the Blair government was always going to lead to situations such as this. The SNP will never be satisfied with the powers that the Scottish Parliament has (which are far in excess of any other group in the UK). Mrs May is quite right to refuse to countenance a second referendum. But what I will say is that if one is held in the future and the vote is to remain in the UK, measures should be taken to reverse the devolution process so that 8% of the UK population do not have the potential to disrupt what happens to the other 92%.
