President Trump told Denmark’s leader he wanted to take over Greenland, European officials say. Denmark has asked its E.U. allies not to inflame the situation until Mr. Trump’s intentions are clearer.

Denmark would need to offer Greenland to the UK first before the island could be sold to Donald Trump, it has emerged. An agreement dating back to 1917 means Britain has first refusal on the Arctic island if current owners Denmark decide to sell it, according to Tom Høyem, Copenhagen’s representative in Greenland from 1982 to 1987.
