The “Scotland isn’t England” message on Covid restrictions now being promoted by the SNP is aggressively combative. This is not a message to pass on information to people entering Scotland from other parts of the UK. Instead, this is clearly a sop to placate the lunatic fringe of the SNP They know a new referendum is off the cards perhaps permanently and so they have to compensate in some way and what better way than to have a go at our southern neighbours, with whom we share this island?
