G7 world leaders met the Queen at an evening reception when a day of political talks gave way to the “soft diplomacy” of the monarchy.
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.
William and Kate are taking part in their first G7 events – another milestone in their progression as senior royals.
The monarchy does not wield power but has influence and uses what is known as “soft diplomacy” to help the UK renew and strengthen friendships with its allies and partners around the world.
Ahead of the arrival of the royal family, many of the G7 leaders, some with spouses, walked through the flora and fauna at the visitor attraction on their way to the reception.
Prime Minister Boris Johnson and wife Carrie were waiting to greet the royal party when they arrived.
The Queen walked just ahead of Charles and Camilla and they were followed a few paces behind by William and Kate.
After a brief exchange of words between Mr Johnson and the Queen, she led the way into the reception and was followed by the senior royals.
Last to arrive after the royal family was US President Joe Biden with First Lady Jill Biden.
