Greenland is a self-ruling territory in the Danish kingdom, which means policymakers in Nuuk control most domestic issues. Denmark, which oversees defense and security policy on the mineral-rich Arctic island, is injecting 14.6 billion kroner ($2 billion) to ramp up defenses.

Mette Frederiksen said Britain was ‘one of our closest and most important allies’ after her dinner with Sir Keir Starmer.

Danish Prime Minister Mette Frederiksen said she now understood the need for the island nation to secure its borders as competition for the thawing Arctic regions heats up.

Greenland's prime minister announced on Tuesday that the semi-autonomous Danish territory will hold a general election on March 11 amid interest by U.S. President Donald Trump in acquiring the Arctic island.

Greenland is bracing for a record influx of American tourists this summer as Donald Trump plots the island’s takeover in a push for military dominance of the Arctic.
