Mercedes González, the director of the Guardia Civil, testified before the Spanish Senate on Tuesday [1].

The appearance follows allegations that the director met with Leire Díez, who is under investigation for a suspected plot to derail judicial proceedings against the Spanish government and the PSOE party [1, 2].

The session was requested by the Partido Popular after the Unidad Central Operativa (UCO) included reports of these encounters in an official document [1, 2]. The UCO is the elite investigative unit of the Guardia Civil, and its findings suggest a link between the director and Díez [1].

However, the reports are contested. Interior Minister Fernando Grande-Marlaska said the director never held meetings with Díez [2]. This contradiction between the UCO report and the Interior Ministry has placed González in a precarious legal position; some reports indicate she could face formal charges as the investigation continues [2].

The investigation focuses on whether Díez operated a network designed to protect government officials from legal scrutiny [1, 2]. If the meetings occurred, they may suggest a breach of protocol or complicity in the alleged plot to obstruct justice [1].

González appeared before the senators on June 16, 2026 [1], to address the discrepancy between the police report and the official government narrative. The proceedings in Madrid highlight the tension between the security forces and the political leadership over the handling of sensitive judicial cases [1].

The UCO included reports of these encounters in an official document

This case represents a significant clash between Spain's internal security apparatus and its political executive. The fact that the UCO—the Guardia Civil's own investigative arm—documented meetings that the Interior Ministry denies suggests either a profound intelligence failure or a deliberate attempt to shield high-ranking officials from a corruption probe. If the director is formally charged, it could trigger a leadership crisis within the national police force.
