Apple could face a massive tax bill in Europe.

FOX's Simon Owen has more from London:

Apple is a leading employer in Ireland, it's home to around a-quarter of the company's European workforce, but the EU today ruling that the Irish government has been trying a bit too hard to keep Apple happy, offering illegal tax breaks:

(Vestager) "This effective tax rate dropped to as little as 0.005%."

EU Competition Commissioner Margrethe Vestager ordering Ireland to reclaim up to $14 billion from Apple in back taxes.

Along with the company, the Irish government also promising an appeal.
