Outgoing European Commission President José Manuel Barroso has taken one final swipe at British Prime Minister David Cameron.<br /><br />Barroso hit out at Cameron over his reaction to a two billion euro EU bill; the row dominated headlines after an EU summit last week.<br /><br />“The British prime minister finished the summit with a diatribe against the EU institutions. This is not acceptable,” the former Portuguese prime minister told euronews in an interview on Tuesday. <br /><br />“Moreover, this is not what we said during the meeting. During the meeting, the discussion was very constructive. He said this bill was a problem for him but he asked to resolve it constructively and that the issue shouldn’t become polemic.”<br /><br />Downing Street says it will not be paying the surcharge, despite the Commission threatening Britain with penalty fines.<br /><br />EU officials say it came about after the methods calculating the size of UK’s economy and its budget contributions were updated.<br /><br />The full interview with José Manuel Barroso will be broadcast on euronews later this week.
