A threat by President Donald Trump to impose fresh tariffs on eight allies opposed to his proposed takeover of Greenland has drawn condemnation from European leaders.

UK Prime Minister Keir Starmer said the move was completely wrong while French President Emmanuel Macron called it unacceptable. Swedish PM Ulf Kristersson said: We won't let ourselves be blackmailed.

The comments came after Trump announced a 10% tariff on goods from Denmark, Norway, Sweden, France, Germany, the UK, the Netherlands and Finland would come into force on 1 February - and could later rise to 25% - and would last until a deal was reached.

Mr Trump insists the autonomous Danish territory is critical for US security and has not ruled out taking it by force.

Meanwhile, thousands of people took to the streets in Greenland and Denmark on Saturday in protest at the proposed US takeover.

Greenland is sparsely populated but resource-rich and its location between North America and the Arctic makes it well placed for early warning systems in the event of missile attacks and for monitoring vessels in the region.

Trump has previously said Washington would get the territory the easy way or the hard way.

European countries have rallied to Denmark's support, arguing that the security of the Arctic region should be a joint NATO responsibility. France, Germany, Sweden, Norway, Finland, the Netherlands and the UK have dispatched a small number of troops to Greenland in a reconnaissance mission.

Announcing the new tariffs on Truth Social, Trump stated, Safety, Security, and Survival of our Planet is at stake, criticizing those nations for playing a very dangerous game.

Starmer emphasized that applying tariffs on allies for pursuing the collective security of NATO is wrong and that the UK will pursue this directly with the US administration.

Other leaders echoed similar sentiments, with Macron asserting that tariff threats are unacceptable and Kristersson revealing that discussions are ongoing among EU countries and allies regarding a joint response.

Denmark's foreign minister Lars Lokke Rasmussen remarked that the threat had come as a surprise.

Opinion polls suggest 85% of Greenlanders oppose the territory joining the US, and recent demonstrations highlight the local demand for respect and self-determination.
