Whereas the Duke and Duchess of Cambridge joined the Queen, Prince Charles, Lady Camilla, Prince George, Princess Charlotte and Prince Louis, on the balcony of Buckingham Palace.
The Sun reported that the Sussexes' meeting with the Queen was kept very brief, quoting a source as saying: "It was a quick in and out job. It was all quite formal."
