British government declares its position on Arctic sovereignty ‘non-negotiable’ amid US tariff threats tied to Donald Trump’s Greenland overtures
The United Kingdom has unequivocally stated that the future of Greenland should be determined solely by the people of Greenland and the Kingdom of Denmark, as diplomatic tensions with the United States escalate over President
Donald Trump’s controversial comments on acquiring the Arctic territory.
Culture Secretary Lisa Nandy insisted that Britain’s stance on Greenland’s sovereignty is “non-negotiable”, rejecting any notion that the UK would entertain external claims or negotiations with the US over the island’s status.
She reiterated that the UK government supports the principle of self-determination and the territorial integrity of sovereign states, while reaffirming its commitment to constructive diplomatic engagement with Washington.
Nandy’s remarks follow President Trump’s threat to impose tariffs of ten per cent on British and other NATO allies’ goods — rising to twenty-five per cent by June — unless a deal to transfer Greenland to American control is reached, a move that has drawn widespread rejection from European capitals.
Prime Minister Sir Keir Starmer has also expressed firm support for Denmark’s authority over Greenland and has engaged in high-level discussions with NATO partners to underscore collective security priorities in the Arctic.
Starmer and other European leaders have criticised the use of tariffs as coercive leverage against allied nations, stressing that cooperation and mutual respect underpin transatlantic relations and regional stability.
British political parties across the spectrum have united in denouncing Trump’s threats, emphasising economic risks and the importance of upholding international law.
As diplomatic efforts continue, the UK has joined Denmark and other European allies in deploying military and diplomatic resources in the region to reinforce Arctic security and deter unilateral actions that could undermine NATO unity.
The reaffirmation of support for Greenland’s self-determination underscores London’s commitment to sovereign decision-making and collective defence in the face of mounting geopolitical contestation over the High North.
