"The Prince, of course, hasn’t seen his grandson Archie for a bit of time and so it was very special to have some time with him," the source explained of Harry and Meghan's 3-year-old son.
The private visit was the first time Charles had met his 1-year-old granddaughter, Lili, and the source said the meeting "was very emotional, a very, very wonderful thing."
As for Harry and Meghan's return to the U.K., a senior royal source at the briefing of Clarence House’s annual review said, “It was fantastic to see them. It was wonderful to have them back in Britain."
"The Prince and the Duchess were absolutely thrilled to see them," the royal source added of Charles and Camilla.
During their trip, Queen Elizabeth was also introduced to Lili, who is her namesake, in person for the first time. Harry and Meghan had previously spent time with the Queen in April. "Being with her, it was great. It was just so nice to see her," Harry said during an interview with Today’s Hoda Kotb that same month. "She’s on great form. She’s always got a great sense of humor with me," Harry said of his relationship with his grandmother. "It was really nice to catch up with her."
