IF, AS reported, any kind of sensitive information with regard to the UK nuclear submarine force is being kept from the SNP by the UK authorities, it is basic common sense. Just think of any of the Green Party, now in coalition with the SNP, having access to any kind of secret material. The very thought is terrifying. The SNP/ Green administration in Scotland, or their MPs in Westminster, should not be allowed within a mile of anything that could be of even minute value to those who would harm this country given the opportunity.
