A new book by journalist Jaime Peñafiel alleged that King Felipe of Spain was deeply affected by revelations of Queen Letizia's infidelity. In the book "Letizia's Silences," Peñafiel claims that Letizia had an affair with Jaime del Burgo, a relationship supposedly known to her bodyguards. Del Burgo, once married to Letizia's sister, reportedly continued the affair even after Letizia married Felipe in 2004.
