**The World Trade Organization (WTO) will rule later on the biggest trade dispute in its history - between aircraft manufacturers Boeing and Airbus.**The US has accused the EU of handing out illegal subsidies to Airbus, and the WTO is widely expected to agree.
However, the EU has made a counter claim against the US for its support of Boeing. A ruling on that claim is due in the next six months.
The WTO’s ruling will come after five years of deliberations.
Experts say its decision will set the boundaries for acceptable government funding in civil aviation.
Louis Gallois, the chief executive of Airbus’s parent company EADS, has said he believes the company has a “very good case”.
