Princess Cristina, the youngest daughter of King Juan Carlos of Spain, has been called to testify on charges of committing fraud and money laundering, an investigating judge announced Tuesday.
The princess is a suspect in a corruption case involving her husband, former Olympic handball player Inaki Urdangarin, dpa reported.
Urdangarin and his former business partner Diego Torres are being investigated over allegations they embezzled more than 6 million euros (7.8 million dollars) in public funds through a charitable institute.
It is the second time that judge Jose Castro has called the princess to testify in the investigations involving the Noos Institute. The first testimony, in April, was suspended after evidence was presented to the court by the Spanish anti-corruption authorities, who have publicly opposed the charges.
The princess is scheduled to appear before the court on March 8.
The Royal Palace expressed its "respect for judicial decisions."
Cristina, 48, is the second of King Juan Carlos and Queen Sofia's three children, and the seventh in line to the throne. She and her husband are the first members of the royal family to be made criminal suspects.
