Leire Díez, a member of Spain's Socialist Workers' Party (PSOE), faced an unexpected disruption during her press conference on Wednesday when businessman Víctor de Aldama confronted her with accusations.

Aldama, currently under investigation related to the Koldo case, entered the conference room towards the end of Díez's statements, labeling her a "sinvergüenza," a term used in Spain to describe someone seen as dishonorable.

He claimed that Díez had mocked the Spanish public and indicated intentions to file a lawsuit against her.

Díez had been in the spotlight for over a week, having announced her voluntary resignation from the PSOE the previous day.

During the press conference, held in a hotel in Madrid, she responded to allegations suggesting that she was collecting information on judges, prosecutors, law enforcement agents, and political rivals—a role depicted as a "fontanera" or fixer within party circles.

Before the incident with Aldama, Díez provided a brief defense to journalists concerning her departure from the PSOE.

She categorized herself as both a journalist and a citizen entitled to rights, asserting that she had spent years investigating the hydrocarbon case, which gained notoriety with the emergence of the "Operación Kitchen" and allegations regarding a politicized police force.

She asserted that her research had uncovered "serious crimes" that had political ramifications, having gathered information on both scandals and the PSOE party itself over several years.

Díez claimed that her recent media prominence stemmed from an "illegal recording" that would also be part of her investigative efforts, while also alleging that she had been the target of fabricated leaks.

She humorously noted that only the leaks tied to the Attorney General were being investigated.

In response to accusations regarding her intentions to obtain "dirty laundry" from legal officials, she remarked on a "misinterpretation" of her aims, while acknowledging possible miscommunication on her part.

During the press conference, she emphasized that she acted independently, stating, "I do not work on behalf of anyone or represent anyone," and clarified that she held no official position within the PSOE.

She stated that it is imperative for democracy to address any misconduct by public officials.

As she concluded her statements without taking questions, Aldama approached the podium, escalating the tension momentarily.

Prior to her press appearance, Díez spent over two hours at the PSOE headquarters discussing her case with the party’s investigator, Alberto Cachinero.

This meeting was part of an information report initiated by the party to clarify various media reports about her activities.

Her voluntary resignation allows her to take the initiative in severing ties with the party, thus prompting the suspension of potential disciplinary measures against her.

At the conclusion of her statement, Díez formally requested the voluntary resignation from her party membership, citing internal regulations that prohibited her from conducting personal interviews or discussions.

She planned to provide her account of events at a subsequent gathering with journalists, now detached from the political organization.

Díez communicated her reasons for leaving directly to the PSOE’s Secretary of Organization, Santos Cerdán, which drew attention to her direct access to high-ranking party officials despite her claims of being an ordinary party member.

The PSOE had previously initiated an information inquiry against Díez approximately one week prior, the lowest level of disciplinary action available, a decision prompted by significant internal and media pressure.

Though the party could have pursued her expulsion due to serious infractions causing reputational harm, they opted for this preliminary inquiry process.
