The monarch's last meeting with a US president was with Donald Trump in June 2019, which saw the Trumps attend a state banquet at Buckingham Palace alongside members of the royal family, including the Prince of Wales, the Duchess of Cornwall and the Duke and Duchess of Cambridge.
The Bidens are no stranger to royalty and have struck up a sweet friendship with Prince Harry over the years.
