The eldest son of Bulgaria's ex-king Simeon Saxe-Coburg Gotha and his wife suffered serious injuries after a heavy crash that occurred late on Friday on a Madrid highway.
Prince Kardam, 46, and his spouse Miriam Ungria survived after their car hit into a tree and overturned.
Emergency services transferred the prince to the Doce de Octubre hospital in the Spanish capital by helicopter with head and hand injuries.
Mrs. Ungria, 45, is in the La Paz hospital in north Madrid with lesser injuries.
There are no confirmed reports of the couple's present condition.
The two married in 1996 and have two sons - Boris and Beltran.
Simeon Saxe-Coburg was king of the Balkan state for three years until 1946 when the communist regime abolished the monarchy and sent the royals into exile. He returned to Bulgaria in 2001 and was prime minister until 2005.
