The brother-in-law of Spain's King Felipe VI has been told by judicial authorities that he has to enter prison within five days to serve a sentence of five years and 10 months for fraud and tax evasion, among other crimes.

Spain's public broadcaster TVE showed Inaki Urdangarin arriving Wednesday by car at the Palma de Mallorca court after landing on a commercial flight from Geneva, where the 50-year-old lives with his wife, Princess Cristina.

The case centered on accusations that Urdangarin embezzled about 6 million euros ($7 million) in public funds. The court found that Urdangarin and his business partner Diego Torres exploited the duke's "privileged status" to obtain public contracts related to sports events.
