Stephen Flynn, SNP leader at Westminster, was lightning fast in diving in to demand the UK returns the Elgin Marbles to Greece after the cancelled meeting of the UK and Greek and leaders over this vexed issue. In opportunism Mr Flynn is first class — in the ability to think things through, like all his SNP colleagues, he is an abysmal failure. Were his demand granted, all the works of art of foreign origin in Scotland’s galleries and even private homes, no matter if paid for or not, would be subject to Mr Flynn’s edict and returned to the source country. Or would he have one law for Scotland and another for everyone else? Alexander McKay, Edinburgh.
