King Charles and Joe Biden appeared to share a joke as the US president was welcomed to Windsor Castle on Monday.
The two men could be seen smiling and laughing with each other as the King welcomed Mr Biden in the castle quadrangle this afternoon, just hours after meeting Prime Minister Rishi Sunak in Downing Street.
On arrival, Mr Biden received the royal salute and the US national anthem was played by the band of the Welsh Guards. He and Charles then inspected the guard of honour before they headed into the castle for tea.
