Princess Cristina, the younger of Spanish King Juan Carlos' two daughters, will appear in court Feb. 8 - a month earlier than originally planned - to answer questions about alleged tax fraud and money laundering, the judge hearing the case said Monday.

Investigating magistrate Jose Castro was responding to a document presented last Saturday by Cristina's lawyers, in which she refused to challenge the summons and stated her wish to testify, though she "absolutely and firmly disagrees" with the charges.

Though her attorneys did not expressly ask for the date of her court appearance to be moved up, her document "makes it obvious that the affected party wishes to shorten the time," Castro said.

Cristina will testify in the corruption case involving the Noos Foundation, which was run by the princess' 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.

Judge Castro maintains that sufficient evidence exists that the princess participated in making Aizoon, the company she owns jointly with Urdangarin, "serve as an indispensable platform for committing tax fraud" and spent company funds perfectly aware of their illicit origin.

The princess had expressed her interest in testifying before the judge "the sooner the better," one of her attorneys, Miquel Roca, told reporters Monday. EFE
