Donald Trump has said he plans to talk to the King about “everything” during the royal state visit, including the Iran war which has strained transatlantic relations. The US president also said he would raise the thorny issue of Nato, which he has lambasted throughout the conflict. The American leader made his comments to Reuters as fresh controversy flared over reports the US could review its position on Britain’s claim to the Falkland Islands as punishment for Sir Keir Starmer’s lack of support for the military action against Tehran.
