The former king of Greece, Constantine II, who is also the godfather of the Duke of Cambridge, was reported to have suffered a heart attack.
Several media outlets reported that the former king, aged 79, had been admitted to a private hospital in Marousi, Athens.
Following several news articles, the Greek Royal House issued a statement denying the hospitalisation of the former monarch.
A spokesperson said: “His Majesty King Constantine is in good health and is not in the hospital as the tabloids have published, if so, he would have made an official statement from his office.”
Constantine had a stroke in 2018 and has been seen using a wheelchair from time to time. He is known to attend different engagements with a walking stick.
Constantine was born in 1940 in Athens, and is the only son of Paul and Frederica. His older sister is Queen Sofia of Spain and his younger sister is Princess Irene.
The former king reigned in Greece from 1964. The abolition of the Greek monarchy in 1973 saw him dethroned. He has five children with Anne-Marie, sister of Queen Margrethe II of Denmark. Their children are Alexia, Pavlos, Nikolaos, Theodora and Philippos. Though they are not an official monarchy, they still use titles at various social appearances.
Constantine is close friends with Prince Charles, his second cousin, and attended Prince William’s wedding to Kate Middleton in 2011 as well as numerous other engagements.
