King Charles III waves to the crowd as he arrives at Windsor Castle for an Easter Sunday church service.

Charles, 75, joined the Queen and other royals in his most significant public appearance since he was diagnosed with cancer.

However, the Princess of Wales and her family did not attend the funeral, just over a week after Kate posted an emotional video message revealing she had started preventive chemotherapy.

Although the Easter service was held inside the castle, the king and queen’s arrival was seen by the media.
