The World Trade Organization (WTO) has given its long-awaited ruling on the biggest trade dispute in its history. The decision, which is officially confidential, is over whether the European Union gave illegal subsidies to planemaker Airbus as the US argues. The Wall Street Journal and others reported that the WTO had found in favor of the US position. But a UK government source told the BBC that the WTO verdict was much more of a “mixed outcome”. “The decision really questions the wisdom of taking this to the WTO in the first place,” the UK source said. Both US and European diplomats have declined to officially release the ruling. The decision is not expected to be officially made public for at least several months. The EU has also made a counter claim against the US for its support of Boeing.
