PRINCESS Cristina is refusing to testify in the ongoing Noos corruption trial.
The Spanish royal was set to speak at the trial in Mallorca last week but has now confirmed she will remain silent throughout the case.
King Felipe’s sister has instead requested that any questions the prosecution has for her should be submitted in a letter to her defence lawyers.
The Princess is one of 18 defendants charged in a corruption trial, also featuring her husband Iñaki Urdangarin, an Olympic handball medallist turned businessman.
Cristina, 50, faces two counts of tax fraud, carrying a maximum prison sentence of eight years, for allegedly failing to declare taxes on personal expenses paid by a property company she owned with her husband.
Urdangarin testified in court last week, admitting his company had fake workers on its payroll.
He is accused of channelling €6.2 million earned in business contracts to private companies and faces a maximum of 19 years in prison.
