Northern Ireland risks becoming “collateral damage” in President Donald Trump’s trade wars despite the UK being hit with a lower tariff than the EU, politicians and business leaders have warned.

US president Donald Trump has imposed sweeping tariffs on imports, including 20 per cent on goods from the EU and 10 per cent from the UK, leaving Northern Ireland in an uncertain position and, as a result of Brexit, a unique one. Northern Ireland is part of the UK, so its exports face 10 per cent tariffs.
