Canadian aerospace firm Bombardier has won a landmark case in the US, overturning a decision to impose huge 292% tariffs on imports of its C-Series planes, partly built in the UK. <br/><br/>It follows a ruling by the US Commerce Department in December that the UK and Canada had given it unfair subsidies. Bombardier had been widely expected to lose the case, which followed a complaint by its US rival, Boeing.<br/><br/>But in a surprise ruling, the US International Trade Commission (ITC) ruled in favour of the Canadian firm.<br/><br/>UK Prime Minister Theresa May welcomed the ruling. She said it was "good news" for UK industry. It safeguards thousands of jobs in Northern Ireland. But it's seen as a blow to US President Trump's "America first" trade policy.
