State and Apple's joint appeal over €13bn tax bill to be heard in Luxembourg today

The European Commission ordered the tech giant to pay over €13bn in back taxes and interest to Ireland to make up for the shortfall.

The State's appeal of the Apple ruling will be heard by Europe's second highest court in Luxembourg later today in what is being described as the world's biggest tax case.

A two year investigation by the European Commission concluded in 2016 that the Irish state allowed Apple to pay far less tax than other companies.
