King Charles and Queen Camilla met Prince Harry, his wife Meghan and their two children on Friday at Charles' Highgrove estate in western England, a palace source said.
It was Charles' first meeting with his grandchildren, Archie, 7, and Lilibet, 5, since 2022. Harry has visited Britain once or twice a year since moving to the U.S. with Meghan and their children, following a high-profile rift with his father and elder brother, Prince William.
The palace source described the meeting as a private family occasion and said no photos, video or further details would be released.
Harry had appeared to be in a dispute with Buckingham Palace over security arrangements and where he would stay, before arriving for five days of charity events and the judgment in a major privacy case he brought against the British media.
Charles, 77, is undergoing treatment for cancer and has rarely seen his two grandchildren since their births. Harry said last year he wanted to reconcile with his family, saying he did "not know how much longer my father has."
Harry lost a privacy case this week against the publisher of the Daily Mail, an action his father reportedly likened to "a suicide mission."
Harry, 41, has been estranged from most of his family since stepping down as a working royal six years ago and criticizing them in interviews and his 2023 memoir, "Spare."
Friday's meeting was the first time father and son had seen each other in person since September.
Harry had wanted to bring his children earlier in the trip, but the family did not reach an agreement with the government on a police protection deal.
Last year, he lost a court battle over security arrangements, which he has said contributed to the breakdown of his relationship with his father.
