The Queen hosted G7 world leaders at an evening reception when a day of political talks gave way to the "soft diplomacy" of the monarchy. There, the Queen met US President Joe Biden for the first time.
Three generations of the royal family were present for the event staged at the Eden Project in Cornwall for presidents and prime ministers and their partners. The Queen was joined by the Prince of Wales, the Duchess of Cornwall, and the Duke and Duchess of Cambridge.
At one point during the photocall the Queen joked: "Are you supposed to be looking as if you're enjoying yourself?'
