Iñaki Urdangarin Liebaert is a retired Spanish handball player turned entrepreneur and the former husband of Infanta Cristina, younger daughter of King Juan Carlos and Queen Sofía. He was the brother-in-law of King Felipe VI. Urdangarin was convicted of embezzling about 6 million euros in public funds for sporting events since 2004 through his nonprofit foundation, the so-called Nóos case, and of political corruption by using his former courtesy title of consort Duke of Palma de Mallorca as the husband of Infanta Cristina. In June 2018 he was sentenced to 5 years and 10 months in prison; he was initially imprisoned in Ávila, but as of 2021, he was on supervised release.

Infanta Cristina is the younger daughter of King Juan Carlos I and his wife, Queen Sofía. She is sixth in the line of succession to the Spanish throne, after her brother King Felipe VI's children, her sister Infanta Elena, Duchess of Lugo, and Elena's children.
