A Spanish judge on Tuesday summoned Princess Cristina, the younger of King Juan Carlos's two daughters, to appear for questioning on charges of tax fraud and money laundering.

The court appearance is set for March 8.

Judge Jose Castro communicated the charge in an order summoning the parties to the corruption case involving the Noos Foundation, which was run by Cristina's husband, Iñaki Urdangarin.

Urdangarin and former partner Diego Torres are accused of embezzling more than 6 million euros ($7.7 million) after using the royal son-in-law's connections to obtain lucrative, no-bid public contracts for the foundation.

This is the second time that Castro has summoned the princess on such charges.

The first time, last April, a higher provincial court suspended the charges at the behest of the office of the anti-corruption prosecutor.

The provincial court, however, authorized Castro to pursue possible tax charges against Cristina, who moved to Geneva last year with her children to work for a Spanish bank's foundation.

In particular, the tax office was told to probe whether she made use of funds from Aizoon, a company she owns jointly with Urdangarin, for personal expenses such as refurbishing her home in Barcelona.

On Dec. 9, Judge Castro asked the parties to declare on the charges against the princess.

Only the activist group Clean Hands, which has pressed the case using a Spanish legal mechanism known as the people's accusation, has said it favored Castro calling on the princess to testify.

Government prosecutors and the attorneys representing Urdangarin, Torres and Cristina said they were against charges being brought against her.

The prosecutor in the case, Pedro Horrach, said in his last document to the judge that the investigation of the princess has not revealed "incriminating evidence that could lead to her facing charges."

The investigation of Urdangarin is "something of a martyrdom" for the Spanish crown, having to see "this subject being echoed day after day," palace chief of staff Rafael Spottorno said in an interview that aired last Saturday on state-run Television Española. EFE
