The escalating dispute over Greenland has triggered the most severe crisis in transatlantic relations in decades, as President Trump threatens new tariffs on several European countries. The prime minister is seeking to negotiate with Trump to avoid the levies, while firmly maintaining Denmark's sovereignty over Greenland. European leaders have issued joint statements condemning the tariff threats and emphasizing their commitment to Arctic security as a shared interest, clarifying that recent military exercises in Greenland were not directed against the United States. Amid concerns that the US is shifting away from multilateral cooperation and undermining traditional alliances, the UK and its partners are working to de-escalate tensions, though uncertainty remains over the future of NATO and the broader global order. The prime minister is expected to continue advocating for sensible trade relations and reaffirm the UK's close ties with the US, while also highlighting the importance of international engagement for domestic economic stability.
