Earlier this week, Apple was ordered to pay a record sum of 13 billion euros plus interest after the EU said Ireland illegally slashed the iPhone make's tax bill. At the time, Tim Cook found the accusations "baseless." In a new interview, he had more things to say:A war of words has erupted between Europe's competition chief and Apple CEO Tim Cook after Ireland was ordered to reclaim $14.5 billion in back taxes from the company. Cook, in an interview with the Irish Independent, labelled Brussels' competition chief Margrethe Vestager's decision as "total political crap." He claimed Ireland was being "picked on" and that he hoped to see the Irish government launch an appeal against the ruling. Vestager refuted that claim when quizzed by reporters on Thursday. "This is a decision based on the facts of the case. The figures that we used in our decision are the figures that we got from Apple themselves," she said. "There are very, very few figures in the public domain. More transparency would be a good thing, for example, a country by country reporting. If it was up to me, the non-confidential version of the decision would have been published yesterday, because that is another way of enabling everyone to see what we have decided and on what basis we have made this decision. Right now the ball is in the hands of Apple and Ireland."
