A personal diary seized from Leire Díez, a former member of Spain’s ruling Spanish Socialist Workers’ Party (PSOE), contains at least four references to Prime Minister Pedro Sánchez, according to a report by the Central Operative Unit (UCO) of the Civil Guard.
The entries, contained in a 2025 notebook, range from meetings and requests for information to comments about the media and internal government affairs.
In that report, the UCO said that the initials “P.S.” that appear repeatedly in Díez’s notebooks refer to Sánchez.
That identification comes via an entry in which Díez herself refers to David Sánchez, the prime minister’s brother, as “brother of P.S.”.
Investigators include that excerpt in the context of what they describe as a “possible strategy” to derail the legal proceedings concerning the brother of the head of government.
According to the report, that strategy is said to have envisaged two avenues: challenging the judge in the case after applying to join the proceedings as a popular prosecution and trying to replace David Sánchez’s lawyer. Both options appear in Díez’s own notebooks.
One of the entries lists a first point that reads: “Be the lawyer for P.S.’s brother,” followed by a second: “Enter as a popular prosecution.” The UCO dates these moves to March 2025.
The report also points to the party’s former number three, Santos Cerdán, as the driving force both behind the hiring of the lawyers who devised those steps together with Díez, and behind the payment of the trips she made to attend various meetings.
Among the most significant references in the diary is an entry dated 3 February 2025 in which Díez notes a “meeting with P.S.”, alongside other references linked to the Koldo network. On another earlier page there is an entry that reads: “Copy, USB stick, chain of custody, queries of Ábalos and P.S. databases,” apparently relating to former minister José Luis Ábalos.
A third reference places the prime minister in the media sphere. Díez wrote: “When Joseph arrives at Prisa he reaches an agreement with P.S. The editorial line is set by P.S. and the strategy by Joseph,” apparently alluding to Joseph Oughourlian, chairman of the Prisa Group. The notebook also contains sentences without initials, such as “The UCO has all the WhatsApp messages between the prime minister and Ábalos” or “Pedro doesn’t trust the DAO.”
For its part, the government has ruled out the notes providing any indication of criminal activity, even if the initials do in fact refer to Sánchez and has concluded that there are no grounds to call him to give evidence as a witness.
