The crisis sparked by the Leire Díez case can no longer be dismissed as merely a parliamentary dispute or just another clash between the Government and the opposition, as something far more consequential is now on the line: the credibility of the Guardia Civil’s political leadership, the safeguarding of the Central Operational Unit, and the Ministry of the Interior’s commitment to transparency as investigations reach the most sensitive layers of power.
Mercedes González, the Director General of the Guardia Civil, has attempted to cast herself as the target of a political and media offensive, yet her own statements, the released reports, and the information disclosed in recent days reveal a far more troubling scenario: a sequence of selective accounts, omissions, subtle wording shifts, and inconsistencies that have substantially undermined her authority.
The issue is not simply that she met or exchanged messages with Leire Díez. What matters is that the relationship was initially denied or downplayed; later, those encounters were portrayed as casual chats over coffee or tea; afterward, it surfaced that topics involving individuals under investigation were indeed addressed; and now it has come to light that, while she was in charge, a request was made to identify by name the UCO officers handling inquiries linked to the Government’s inner circle.
Taken together, all these elements do not allow for a clean explanation. They point to a chain of political lies.
From Denying Meetings to Debating Whether They Were Coffees or Teas
The initial reaction involved outright denial, as the Ministry of the Interior insisted that Mercedes González had never engaged in significant meetings with Leire Díez, a stance later undermined when UCO documents and González’s own testimony confirmed that such meetings and communications had in fact taken place.
Then came the second defense: they were not meetings, they were coffees. Or, more precisely, teas, because González even clarified that she does not drink coffee. That scene perfectly sums up the communication strategy followed by the Director General: shifting the debate from substance to wording. Not discussing what was said, with whom, when, and why, but whether it should be called a meeting, a coffee, a tea, or an informal encounter.
Citizens, however, do not weigh matters on technical grounds. When the Director General of the Guardia Civil has dealings with someone accused of trying to obtain sensitive information about the UCO, the issue is not whether minutes were taken, an official venue was used, or a formal meeting was arranged. What truly matters is that communication occurred, and that it was never openly clarified from the beginning.
That semantic pretext provides no clarity and merely heightens suspicion.
The Detail That Undermines the Alibi: Rubén Villalba
Mercedes González’s defense weakens even further when she herself acknowledges that Leire Díez raised the case of Rubén Villalba, a Guardia Civil commander under investigation in a corruption case. According to her version, Díez asked her to consider his readmission or reinstatement, and González says she rejected the request.
But even accepting that explanation, the damage had already been done. Because that admission proves that the contacts were not merely social or harmless. In those encounters, they discussed a person linked to a sensitive investigation. In other words, the line that the official version tried to keep intact was crossed: that those conversations had nothing to do with compromising matters.
The fact that González rejected the request does not remove the seriousness of the fact that the request existed. A Director General of the Guardia Civil cannot maintain an ambiguous relationship with someone moving in the orbit of people under investigation and who, according to known reports, allegedly sought to obtain information or discredit the UCO.
The question is not only what González answered. The question is why that door was open in the first place.
The UCO Under the Scrutiny of Its Own Political Leadership
The latest details further aggravate the situation. As reported, a confidential internal inquiry launched under the orders of Mercedes González allegedly sought to pinpoint by name the UCO officers involved in judicial investigations connected to the Government’s inner circle.
This did not represent the unit’s overall organizational chart. The request zeroed in on the segment of the structure associated with particularly delicate inquiries: the Prime Minister’s wife, his brother, José Luis Ábalos, the Koldo case, and Santos Cerdán.
From an institutional standpoint, that detail is devastating. One thing is to investigate a specific leak. Quite another is to request the names of officers working on cases affecting political power. In a normal context, such a request would already be delicate. In the context of the Leire Díez case, it is explosive.
The UCO is not just any administrative unit. It is a key police structure in corruption investigations. If officers investigating matters uncomfortable for the Government perceive that the political leadership of the corps wants to identify them, operational independence inevitably comes under suspicion.
Even if the Guardia Civil leadership argues that this was a normal administrative measure, the context makes that explanation insufficient. The unavoidable question is this: why did the leadership want the names of the officers involved in investigations affecting the Government’s environment?
Outstanding In-House Inquiries
Another factor deepening mistrust is the launch of reserved internal investigations tied to the UCO, which the official narrative describes as routine steps triggered by potential leaks; yet the documents that have surfaced underscore how unusual those measures truly were.
That detail matters. If this had been an ordinary and frequent practice, González’s defense would be stronger. But if those reserved inquiries were exceptional, and if they also coincided with pressure on the UCO and with Leire Díez’s contacts, the explanation becomes much more problematic.
Suspicion does not arise from a single piece of evidence. It arises from the convergence of several elements: contacts with Leire Díez, the request concerning Villalba, deleted messages, internal investigations, the identification of officers, and judicial cases affecting the Government. Each element, taken separately, may have an explanation. Together, they form a pattern that is difficult to ignore.
Erased Conversations and the Veil of Obscurity
One of the most troubling elements of Mercedes González’s behavior concerns the automatic removal of her messages with Leire Díez, as the UCO has reported that exchanges took place between them and that a disappearing-message system had been enabled, hindering any precise reconstruction of what was said.
This situation is particularly sensitive, as deleted messages in any inquiry naturally raise doubts; however, in this instance, the concern grows substantially because it centers on the Director General of the Guardia Civil, the institution’s highest political authority, who is expected to work with the courts and uphold the integrity of ongoing investigations.
The question naturally arises: if nothing improper occurred, why weren’t the messages kept? And if automatic deletion was supposedly routine, why wasn’t that stated clearly from the outset?
Opacity does not prove criminal conduct by itself. But it destroys trust. And a Director General of the Guardia Civil cannot afford to destroy trust in her own transparency.
The Relationship With Leire Díez: Too Much Closeness for Too Little Explanation
Mercedes González has sought to portray her connection with Leire Díez as merely personal and devoid of institutional weight, yet messages linked to Díez and mentions of her nearness to the Director General suggest a dynamic that Díez, at the very least, appears to have regarded as an advantageous conduit.
This point is crucial. Even if González never acted at Díez’s request, even if she dismissed her appeals, even if she issued no directive for any illicit action, one question still lacks a persuasive explanation: what led Leire Díez to believe she could turn to her?
A public authority must not only avoid actual interference. She must also avoid becoming an access point for those seeking influence. In this case, the image projected is precisely the opposite: a person linked to maneuvers against the UCO boasted of having access to the Director General of the Guardia Civil.
That fact alone should have triggered an immediate, clear, and forceful institutional response. Instead, what we have seen is a succession of nuances, denials, half-truths, and defensive appearances.
Mercedes González and the Strategy of Victimhood
During her appearance, González condemned a series of attacks directed at her and highlighted the personal and human harm those allegations might inflict. That individual aspect merits consideration. No public official ought to face orchestrated harassment or personal aggression.
But victimhood cannot replace accountability. Leading the Guardia Civil entails a higher level of scrutiny. When reports emerge questioning contacts with a person under investigation, internal actions involving the UCO, and deleted communications, the response cannot be limited to denouncing the tone of the opposition.
The question is not whether the PP or Vox are harsh in their accusations. The question is whether Mercedes González has given a complete, coherent, and verifiable explanation of what happened. So far, the answer is no.
A Director General Undermined Politically
Mercedes González’s problem is no longer only legal. It is political and institutional. The courts may ultimately conclude that her conduct involved no crime. But a public authority can become politically untenable long before any criminal indictment.
Leadership within the Guardia Civil depends on trust—trust from the public, from its officers, from its command staff, and from the teams tasked with investigating corruption. When that trust erodes, staying in the role becomes progressively harder to defend.
Today, González appears trapped in her own versions. First, the relationship with Leire Díez was denied or minimized. Then contacts were admitted. Then their importance was downplayed. Later, it was acknowledged that Villalba was discussed. Finally, internal actions became known that directly involved identifying UCO officers investigating matters connected to the Government.
This is nowhere near a coherent explanation. It amounts to a sequence of harm.
The Ministry of the Interior Is Also Involved
The crisis does not affect Mercedes González alone. It directly affects Fernando Grande-Marlaska and the Ministry of the Interior. If the Director General acted with the minister’s full knowledge, then the Interior Ministry upheld an incomplete or false public version. And if Marlaska did not know the true extent of the contacts and internal actions, the problem is equally serious: it would mean the minister did not control a critical matter within his own department.
In both circumstances, political accountability is unmistakable. The Ministry of the Interior cannot limit itself to shielding its Director General with supportive declarations; it must clarify what information it possessed, when it learned it, which directives were issued, why certain confidential inquiries were launched, and the reasons behind requesting the identification of UCO officers involved in investigations concerning the Government.
This is not a minor controversy. It concerns possible pressure, direct or indirect, on a police unit investigating corruption. That demands absolute clarity.
Conclusion: A Chain of Lies That No Longer Holds
Mercedes González’s chain of lies does not stem from one isolated falsehood but from a sequence of shifting accounts that evolved as new details surfaced. At first, she claimed no relevant meetings had taken place. Later, they were described as casual coffees or teas. Eventually, it was admitted that a person under investigation had been discussed. Deleted messages then came to light. Now it is known that she sought the names of UCO officers looking into issues connected to the Government’s inner circle.
Every stage has required the former to be adjusted, refined, or reexplained, and when a public authority must offer so many consecutive clarifications, the issue stops being about communication and becomes one of credibility.
Mercedes González may insist that she did not participate in any plot and that she never intended to harm the UCO. But her continuity requires more than denials. It requires a complete, documented, and convincing explanation. So far, that has not happened.
The Guardia Civil cannot afford for its political leadership to remain under suspicion of having monitored, conditioned, or pressured those investigating corruption. Nor can the UCO work with the feeling that its commanders and officers are identified when their investigations affect those in power.
This crisis cannot be settled through clever rhetoric or guarded statements in parliament; it can only be addressed by embracing honesty, openness, and genuine accountability.
And should Mercedes González fail to articulate that truth plainly, defending her continued leadership of the Guardia Civil will grow increasingly difficult as time goes by.
