Foreign minister hits out after US president-elect refuses to rule out military action to take control of Greenland

France has warned Donald Trump against threatening the “sovereign borders” of the European Union after the US president-elect refused to rule out military action to take control of Greenland, an autonomous territory of EU member Denmark.

The French foreign minister, Jean-Noël Barrot, told France Inter radio: “There is no question of the EU letting other nations in the world, whoever they may be, attack its sovereign borders.”
