A Spanish judge has formalised charges against Princess Cristina, King Felipe's sister, in a tax fraud and money laundering case.The princess, 49, was questioned in court in February about the business dealings of her husband, Inaki Urdangarin, and could now face trial.However, an appeal has been lodged against the decision.The judge's ruling will come as an embarrassment to Felipe VI, who came to the throne only six days ago.The tax fraud case was one of several scandals that weakened the popularity of the Spanish monarchy and prompted the abdication of King Juan Carlos.Princess Cristina's appearance in court in Mallorca was unprecedented for the royal family and if she goes to trial, she could face up to 11 years in jail.She was noticeably absent from Felipe's proclamation as king.The judge's decision is a major development in this investigation and a huge embarrassment for the Spanish royal family.Jose Castro believes the princess knew more than she has let on regarding the allegedly corrupt activities of her husband, Inaki Urdangarin.This inquiry has now lasted more than three years and during that time it has heavily eroded the popularity of the royal family. Princess Cristina has already appeared in court to testify, but the door is now open for her to face trial, which would take the scandal to a new level.Her brother, Felipe, became king less than a week ago. Of the many challenges he faces as the new monarch, this is perhaps the least welcome.(BBC)Bakudaily.az
