Donald Trump has threatened a 10% tariff on eight European allies, including the UK, from February 1 unless they agree to his purchase of Greenland. Ireland, although not among the eight countries threatened, has said tariffs on some member states amounted to tariffs on all member states. Mr Harris, who is Ireland’s deputy premier and finance minister, said that while there is a lot of “noise and threats” about Greenland, “nothing has factually changed”. He said that if the US were to annex Greenland that would “fundamentally alter the transatlantic relationship” and said that that in turn could create a “spiral of events and retaliatory events” across economies and markets. Mr Harris said that the EU was “taken aback” by the threat of tariffs, particularly after an EU-US trade deal was struck last year.
