Donald Trump has threatened to pull all American troops out of Europe as he again berated Nato allies over their opposition to his ambition to annex Greenland.

The president renewed his criticism and claim to the semi-autonomous Danish territory at the start of a crucial NATO summit this week.

He argued that the US needs to take over the mineral-rich Arctic island on national security grounds.

Sir Keir Starmer has previously joined with other European leaders to rally behind fellow Nato member Denmark and insist they would ‘not stop defending’ Greenland’s territorial integrity,fuelling transatlantic tensions.

Responding to a question on the dispute at the meeting in Ankara,Trump said: ‘That’s what hurt my relationship with Nato,because Greenland doesn’t help Denmark.

‘Denmark doesn’t spend money to really help Greenland,but it’s an important part for the United States,and it’s surrounded by Chinese ships and Russian ships,and that’s not going to happen.’
