Tempers flared during Donald Trump's 'horrendous' phone call with Danish PM Mette Frederiksen regarding the purchase of Greenland, according to officials.

President Donald Trump has said he believes the US will gain control of Greenland, after showing renewed interest in acquiring the autonomous Danish territory in recent weeks. "I think we're going to have it," he told reporters on Air Force One on Saturday, adding that the island's 56,000 residents "want to be with us".
