John Wight, the price to the Scottish economy would be enormous as 60% of its trade is with the UK. This is apart from the nightmare of disentangling the integrated countries.
Scotland can do better for itself by steering the UK back into the EU.
Brexit, as you point out, was a huge mistake. Scotland leaving the UK would be a mistake on top of another. Nationalism is fashionable nowadays but comes at the price of prosperity and security.
Many thanks.
