King Charles has taken part in a traditional ritual in Samoa, drinking the ceremonial beverage kava, made from the root of a plant. He was also declared a "high chief" of the archipelago during his trip to the country.

His son Prince Harry has spoken volubly of his fondness for ayahuasca, and King Charles today followed in his footsteps by partaking of a traditional narcotic drink while visiting the Pacific island nation of Samoa on the last leg of his ongoing tour of Oceania.

King Charles III arrived in Samoa on Wednesday to preside over the gathering of Commonwealth presidents and prime ministers for the first time as head of the monarchy.
