King Felipe VI of Spain has stripped the title of duchess from his sister, as she prepares to stand trial on tax fraud charges.
The king has put pressure on his sister Cristina de Borbon to give up her succession rights since the scandal came to light last year.
The move by the 47-year-old king, crowned nearly a year ago after the abdication of his father Juan Carlos, is part of a bid to revive the image of a monarchy tarnished by scandals.
The princess is due to stand trial later this year and will be the first Spanish royal to face prosecution since the monarchy was restored in 1975.
Investigations in Spain have exposed high-levels of corruption throughout society, damaging Spaniards' faith in their institutions.
The title of Duchess of Palma de Mallorca was conferred on Ms de Borbon by her father on her marriage in 1997 to former Olympic handball player Inaki Urdangarin.
Mr Urdangarin has been charged with fraud and embezzling around €6m of public funds following a long-running investigation into his Noos Foundation charity.
Last year, the couple were ordered to stand trial along with 15 others following the probe.
No trial date has yet been set, although the case is expected to come to court in the later this year.
Both have denied any wrong-doing.
