Like a broken record, Westminster's SNP leader Ian Blackford launched into one of his tiresome anti-Brexit rants at Prime Minister's Questions last week. Blackford lambasted Boris Johnson for inflicting 'economic vandalism' on Scotland and demanding a 'detailed economic assessment of the cost to the UK of his extreme Tory Brexit plans'. With Blackford frothing at the mouth, you'd be forgiven for thinking the SNP bruiser — a man who's not short of a bob or two as a former managing director of Deutsche Bank and having pocketed £1.8 million from the sale of internet provider Commsworld, of which he was non-executive chairman, this year — passionately supports Scottish businesses and only Scottish businesses.
