Bombardier faces 220% tariff from the USA

The US Department of Commerce has ruled that Bombardier has received unfair subsidies from the UK and Irish governments, helping it win a major order made last year from US airline Delta.

As a retaliatory measure an interim tariff of 220% has been imposed and there are worries that this will cost jobs, especially in Northern Ireland. 

This raises lots of issues, about trade, unfair trade practices and the role of retaliation in trade disputes. And from a domestic perspective, there's likely to be a negative regional multiplier.
