The Prince of Wales, Prince William, will represent his father, King Charles, at the funeral of Norway's King Harald V, set for September 9 in Oslo. This follows royal protocol that generally dictates reigning monarchs do not attend the funerals of fellow heads of state, a convention which has seen other family members fulfill the role in similar situations, such as William attending the funeral of Pope Francis last year on behalf of his father, according to BBC and South China Morning Post.

Princess Anne, attending in her personal capacity as the godmother of Norway's new monarch, King Haakon VIII, will also be present at the funeral. King Harald, who served as a beloved figure for 35 years and became known for his casual approach and connection with the public, passed away at the age of 89 on August 28, according to India Times and South China Morning Post.

The funeral service at Oslo Cathedral is expected to be attended by large crowds and will include ceremonies honoring the late king. Among the tributes, King Charles expressed his condolences, lauding King Harald for his "unwavering dedication" and describing him as a "kind and compassionate" monarch. The close familial ties between the British and Norwegian royal families add to the significance of the event, as both monarchs are descendants of King Edward VII, according to BBC, South China Morning Post, and India Times.
