MADRID (AFP) ― Spanish King Juan Carlos’s youngest daughter, Princess Cristina, is in the front line of a legal storm engulfing her husband, Inaki Urdangarin, who is under investigation for allegedly embezzling millions of euros in public money.

The 47-year-old has not been named as a suspect in the corruption probe opened at the end of 2011 by a judge on the Mediterranean island of Mallorca.

Urdangarin and his former partner Diego Torres are suspected of siphoning off money paid by regional governments to stage sports and tourism events to the non-profit Noos Institute, which Urdangarin chaired from 2004 to 2006.

Urdangarin, a former Olympic handball player, sought to distance his wife and the rest of the royal family from his business dealings when he was questioned in court last month.

But last week Torres provided the judge with emails that were leaked to the press which appear to show that Urdangarin regularly consulted his wife ― a member of the board of the Noos Institute ― about the body’s affairs.

Carlos Garcia Revenga, the longtime personal secretary to Princes Cristina and her older sister Princess Elena, was questioned by the judge last month after Torres submitted another batch of e-mails that suggested he was actively involved in the Noos Institute’s dealings.
