Diego Torres, the defendant in a corruption case together with his ex-partner,Iñaki Urdangarin, son-in-law of Spain's king, said Saturday before a judge that the Spanish Royal Household and the second daughter of the monarch knew all about the operations of the Noos Institute, the focus of the investigation.

Court officials told Efe that when Torres gave his testimony before the judge in a Palma de Mallorca courthouse in the Balearic Islands, he said that Princess Cristina, Urdangarin's wife, and her secretary, Carlos Garcia Revenga, were members of the institute's board of directors, in which they took as active a part as the rest of its members.

Being investigated in this case is the alleged siphoning off of 6.1 million euros ($8.15 million) in public funds from the regional governments of Valencia and the Balearic Islands to the Noos Institute, a supposedly non-profit organization of which Torres was a partner.

The defense attorney of the Duke of Palma's ex-partner handed over to the judge e-mails and documents to do with the management of the Noos Institute as proof that both the princess and Garcia Revenga were active in taking its decisions.

The charges that Iñaki Urdangarin faces in the Noos case include falsifying documents, breach of public duty, embezzlement of public funds and influence peddling.

Urdangarin and the secretary of the princess have been summoned to testify before the judge on Feb. 23. EFE
