UK Prime Minister Sir Keir Starmer has firmly rejected demands from US President Donald Trump over Greenland, insisting he will not bow to what he described as pressure tactics aimed at forcing Britain to compromise its position on the strategic Arctic territory.
Speaking during Prime Minister’s Questions, Starmer dismissed Trump’s latest remarks, in which the former US president accused him of “great stupidity” over the Chagos Islands and threatened tariffs, calling them an attempt to make the UK abandon its “values and principles.”
“President Trump deployed words on Chagos yesterday that were different to his previous words of welcome and support when I met him in the White House,” Starmer said. “He deployed those words for the express purpose of putting pressure on me and Britain regarding my values and principles on the future of Greenland. He wants me to yield on my position—and I am not going to do so.”
The confrontation comes amid escalating tensions between Washington and European capitals after Trump indicated he would impose 10 per cent tariffs from February 1 unless Britain and the EU supported US control over Danish-owned Greenland. EU Commission President Ursula von der Leyen vowed the bloc would respond “unflinchingly,” while Starmer confirmed that Danish Premier Mette Frederiksen will visit Downing Street for urgent talks.
In a turbulent 24 hours, Trump also threatened 200 per cent tariffs on French wine and champagne, published private messages from French President Emmanuel Macron, and shared AI mock-ups of himself planting a US flag on Greenland. He further revived previous claims on Canada, posting a US-coloured map.
The growing crisis has raised alarms within NATO, with analysts warning of the alliance’s most serious rupture since its founding in 1949. Chancellor Rachel Reeves insisted the UK “would not be buffeted around” by tariff threats, telling broadcasters from Davos: “Britain is not here to be buffeted around. We’ve got an economic plan… If other countries want to increase trade barriers, that is their choice.” She emphasized that the trade deal with Washington “would not be undone.”
The Bank of England is on “high alert,” with Governor Andrew Bailey warning MPs that geopolitical uncertainty could trigger market volatility. Meanwhile, shadow Cabinet minister Alex Burghart described the dispute as “the most dangerous moment for Europe since 1945,” cautioning that a collapse of NATO could embolden Vladimir Putin in Ukraine.
At the centre of the standoff is Greenland, strategically located between the Arctic and North Atlantic. The island is critical for missile defence, high-tech supply chains, and emerging shipping routes. It hosts Pituffik Space Base, the US’s northernmost military installation, and is rich in rare earth minerals essential for defence and electronics. While the US already has broad access through treaties, Trump has incorporated Greenland into his “Golden Dome” missile-shield plan, calling it “vital” to America’s early-warning defence system.
Starmer’s defiance represents his sharpest public criticism of Trump since taking office. He condemned the tariff threat as “completely wrong,” while opposition figures have urged him to convene an emergency Arctic security summit to prevent further deterioration.
As the UK navigates relations with Washington, Copenhagen, and Brussels, Downing Street faces a geopolitical dilemma spanning defence, trade, and strategic resources, with the future of alliance unity hanging in the balance.
