UK Prime Minister Sir Keir Starmer has reiterated Britain’s firm support for Denmark’s sovereignty over Greenland during discussions with Danish Prime Minister Mette Frederiksen, emphasising that only Greenland and the Kingdom of Denmark should determine the territory’s future.

The reaffirmation came as U.S. President Donald Trump revived comments about America’s interest in Greenland on national security grounds, prompting concern among NATO allies.

Starmer’s message underlined the United Kingdom’s backing for a European partner and long-standing NATO ally, asserting that the future of the vast Arctic territory must be decided by its own people and Denmark’s government.

This stance was conveyed during a telephone call on January eighth, in which the leaders also discussed ongoing support for Ukraine and recent coordinated actions such as the interception of a Russian-linked oil tanker by Western forces.

The reaffirmation aligns with broader European resistance to external pressure over Greenland’s status and reflects diplomatic efforts to uphold international law and the principle of self-determination.

Starmer’s comments echo earlier declarations by Frederiksen, who has urged the United States to respect Denmark’s sovereignty amid heated rhetoric suggesting potential American interest in acquiring Greenland, which Danish officials have rejected.

The discussions come at a time of heightened geopolitical competition in the Arctic, where Denmark, Greenland and their allies are focused on security cooperation and maintaining stability in the region.

Starmer’s position has been supported by other European leaders in joint statements affirming that Greenland “belongs to its people” and that the Kingdom of Denmark retains authority over its future.

While the United States remains an important NATO partner in Arctic security, the emphasis from London and Copenhagen has been on multilateral cooperation and respect for established borders.

The UK prime minister’s reaffirmation thus serves both as a gesture of solidarity with Denmark and as a clear diplomatic signal regarding the rules governing territorial sovereignty within the alliance framework, even as debates over broader U.S. strategic intentions continue to reverberate across capitals in Europe and beyond.
