Begoña Gómez, wife of Spanish Prime Minister Pedro Sánchez, faces scrutiny over her role at the Complutense University of Madrid.
An internal report accuses Gómez of bypassing procurement rules in her capacity as director of a university chair.
The report highlights an irregular contract awarded to Making Science company, allegedly without proper procedures.
Additionally, questions have been raised about Gómez's qualifications to lead a university chair and teach, given her lack of a relevant degree.
The university's rector, Joaquín Goyache, testified that Gómez invited him to a meeting at the Prime Minister's residence to propose creating her chair, which was established three months later.
These revelations have sparked calls for explanations from both Gómez and Prime Minister Sánchez.
