King Charles is reportedly saddened by the passing of his esteemed relative, Prince Michael of Greece and Denmark, who was Prince Philip's first cousin.
Prince Michael, a celebrated historian and writer, died at the age of 85 in Athens, as announced by his family on Sunday.
The 75-year-old monarch "has not been feeling well since he received the sad news from Greece," according to a royal insider.
The late Duke of Edinburgh’s first cousin, who was the last remaining grandson of George I, will be laid to rest in the Greek capital on Thursday.
Prince Michael was well known for his marriage to Marina Karella, for whom he renounced his right to the Greek throne in 1965. He is survived by his wife and their two daughters, Princess Olga of Savoy-Aosta and Princess Alexandra of Greece.
The Prince was the only child of Prince Christopher and his second wife, Princess Francoise d’Orléans of France. He studied political science in Paris before returning to Greece for military duty, serving a term in the Hellenic Coast Guard to regain Greek citizenship.
He was the only member of the Greek royal family to remain in the country in 1967 when the government fell to a right-wing military coup after his nephew King Constantine failed in his attempts to overthrow the junta.
Mourning fans of the historian and author have been posting tributes online, honouring his significant contributions and legacy.
