Coffee chain Starbucks has agreed to pay more UK corporation tax, after a public outcry over how little it pays. Kris Engskov, managing director of Starbucks UK, announced that the company would pay "a significant amount of tax during 2013 and 2014 regardless of whether the company is profitable during these years". The extra tax could amount to £20m over the next two years, he said. "We know we are not perfect", the boss of the coffee chain added.
