Sir Keir Starmer is facing increasing pressure to prevent King Charles from embarking on a tour of the United States as allies recoil from Donald Trump’s escalating threats to impose sanctions on Europe if it does not comply with Washington’s demands regarding Greenland.
The British prime minister, 62, is being urged from all corners of Parliament to cancel the King’s planned state visit to Washington this spring after Trump, 79, issued warnings that countries opposing a U.S. acquisition of the oil-rich Danish territory would face significant trade penalties.
In a bold online statement, Trump announced that tariffs would commence at 10 percent on February 1 and could potentially increase to 25 percent by June, specifically targeting the U.K., France, Germany, and Denmark. This intervention has sent shockwaves through NATO allies and raised concerns about the future of the alliance, established eight decades ago.
Simon Hoare, a senior Conservative Member of Parliament, is among those advocating for a strong response. He condemned Trump, stating, “The civilized world can no longer deal with Trump. He is a gangster pirate.” Hoare also urged fellow MPs to reconsider the optics of hosting royal ceremonies while allies are being threatened.
The culture secretary, Lisa Nandy, representing the government, reiterated Britain’s stance on Greenland’s sovereignty. She expressed disapproval of Trump’s actions but declined to comment on whether the King’s visit should proceed, emphasizing the depth of the transatlantic relationship.
Economists have cautioned that new U.S. tariffs could push the U.K. back into a state of economic recession, while senior European parliamentarians have threatened to halt E.U. / U.S. trade negotiations in retaliation. The specter of a renewed global trade war looms large as markets grapple with Trump’s inflammatory rhetoric.
Sir Keir Starmer, known for his efforts to maintain amicable relations with the White House, issued a rare public rebuke of Trump’s tariff threats. He affirmed, “Our stance on Greenland is crystal clear—it is part of the Kingdom of Denmark, and its future is a matter for the Greenlanders and Danes.” Starmer emphasized the inappropriateness of imposing tariffs on allies for safeguarding the collective security of NATO members and pledged to address the issue directly with the U.S. administration.
European leaders, including French President Emmanuel Macron, have condemned Trump’s threats and pledged to coordinate with their European counterparts. Macron emphasized that intimidation and threats would not sway their decisions. Nigel Farage of Reform U.K. expressed concerns about the detrimental impact of the tariffs and criticized Trump’s approach to China in the Arctic.
Former foreign secretary Jeremy Hunt dismissed the notion of a U.S. invasion of Greenland but warned of a tense standoff, stating that such an act would signify the demise of NATO. Trump’s former national security adviser John Bolton labeled the tariff threat as recklessly unprecedented, highlighting the potential repercussions for the special relationship and NATO alliance.
As protests erupted in Denmark and Nuuk with chants of “Greenland is not for sale,” the diplomatic fallout from a potential U.S. tour remains a cause for concern among palace aides. The situation has underscored the delicate balance that the government must navigate in preserving international relationships while upholding its principles and safeguarding national interests.
