Michael Gray is a 21-year-old politics student at Glasgow University. On 7 April, an article he wrote appeared on National Collective, a Scottish independence website. The piece used sources already available online to paint an unalluring portrait of the business dealings of the Vitol Group, an energy trading giant. That day, Better Together (the No campaign) had announced that it had received more than £1.1 million in donations, including £500,000 from Ian Taylor, Vitol’s CEO (and a major donor to the Conservative party).
