By royal decree under Spanish King Felipe VI, Infanta Cristina de Borbon will no longer hold the title of Duchess of Palma de Mallorca, Spain's official state bulletin announced on Friday.
The decision to revoke the titles of Infanta Cristina and her husband Inaki Urdangarin, signed by King Philip VI and Prime Minister Mariano Rajoy, was first announced on Thursday, coinciding with investigations implicating the former duke and duchess in a corruption scandal.
On Friday, Infanta Cristina's lawyer, Miquel Roca, said that she had "expressed her intention to renounce to her title some days ago" in a letter and thus agreed with the king's decision.
However, the royal palace claimed that the letter in which Infanta Cristina renounced her title arrived at the Zarzuela Palace after the king had already informed her of the news.
Investigations into Critsina's corruption case began in 2010 over concerns regarding the Noos Foundation, a non-profit headed by Urdangarin, suspected of squandering 6.1 million euros ($6.84 million) of public funds from 2004 to 2007.
Some of the money is suspected to have been transferred to Aizoon, a company largely owned by Cristiana and her husband.
King Felipe's sister was giving the title in 1997 by her father, the then King Juan Carlos I, upon her marriage to Urdangarin, becoming the Duke and Duchess of Palma de Mallorca.
