MADRID - Spain’s Princess Cristina returned to court in Palma de Mallorca on Tuesday as defendants began to testify in a fraud trial that centers on her husband’s business affairs and has badly damaged the image of the royal family.

King Felipe’s 50-year-old sister became the first member of the Spanish royal family to stand in the dock at a preliminary hearing in January, and she now faces a full trial on tax fraud charges after an appeal by her lawyers was thrown out.

Cristina will be the last of 17 defendants to testify at the Palma court, where the case is being held. It is still unclear when in February she will take the stand.

All of the accused, including her husband, Inaki Urdangarin, must sit through the statements in the public trial, meaning weeks of media scrutiny on the couple at a time when the monarchy is trying to draw a line under family scandals.
