It is with great sadness that we announce that the prince has passed away suddenly tonight
Marina Karella, for whom he renounced his right to the Greek throne to marry in 1965.
He is survived by his wife and their two daughters, Princess Olga of Savoy-Aosta and Princess Alexandra of Greece.
Prince Michael was the only child of Prince Christopher and the royal’s second wife, Princess Francoise d’Oleans of France.
His father died at just 51 in 1940 after suffering from a short illness before his mother died in 1953, leaving the royal an orphan by the time he was 14.
He studied political science in Paris before repatriating to Greece for military duty, where he served a term in the Hellenic Coast Guard in order 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.
