Greenland's pro-business Demokraatit Party surged to victory in a shake-up that could boost U.S. President Donald Trump's attempts to tap the island's mineral wealth, with the victors keen for reforms favouring private enterprise and mining.

The Democratic party, which favours a gradual approach to independence from Denmark - achieved around 30% of the vote, near-complete results show.
