Infanta Christina of Spain attends preliminary hearing for tax fraud trial

Infanta Christina put on a brave face as she arrived at court in Majorca to face legal proceedings for a long-running corruption case, which includes 17 more people. The Spanish princess is sister to King Felipe VI, and is facing the courts along with her husband, Iñaki Urdangarin, who is charged with money laundering, embezzlement and forging documents.

Infanta Cristina is facing trial for tax fraud.

Looking sombre, the couple made their way past scores of journalists from around the world. International attention has focused on the trial because this is the first time a member of the Spanish royal family has faced judicial proceedings.

In this week's preliminary session her lawyers are attempting to argue that the case should be dropped. The three judges on the panel have until Feb. 9 to rule on their arguments.

The accusations centre around the Noos Institute, an non-profit organization for the promotion of sports and tourism that was founded by Iñaki, a towering former athlete who was once the captain of the national handball team.

Iñaki and his business partner are alleged to have diverted around €6.2 million from public contracts to organize sports events into private accounts. The king's sister sat on the board of a company named, Aizoon, that was allegedly used to channel some of these funds.

At a previous hearing the 50-year-old royal answered 'I don't know' to many of the questions or said that she trusted her husband to handle their financial affairs.

Until 2011, Cristina and her husband lived a fairytale lifestyle as part of the country's high society – the title Infanta is given to someone born a princess rather one who has married into the family.

At their glittering 1997 wedding in Barcelona, the infanta was given away by her father King Juan Carlos who conferred on them the title of the Duke and Duchess of Palma de Majorca.

She had four children with the dashing sportsman, who served as captain of the bronze-medal winning team at the 2000 Olympics.

Since her brother ascended to the throne in June 2014, he has emphasized the monarchy's transparency. The king issued a decree stripping his sister of the title of Duchess of Palma.

King Felipe and his wife Queen Letizia are widely regarded as a hard-working and down-to-earth couple, who are seen on the school run with their daughters and dining quietly in trendy areas of town.
