The purpose of the investigations is to ascertain whether there are sufficient grounds to proceed with formal inquiries based on open-source information and documents from the involved parties.

While the investigation into Pedro Nuno Santos has been open for over a month, specific details regarding it have not been disclosed by the PGR.

The Public Prosecutor's Office (PGR) has confirmed ongoing preventive investigations involving Prime Minister Luís Montenegro and Secretary-General of the Socialist Party, Pedro Nuno Santos, related to the acquisition of a property in Lisbon.

The investigation into Montenegro was initiated after three complaints concerning his family's company, Spinumviva, were received, prompting the need to determine if a formal inquiry is warranted.

As of May 20, 2025, the PGR is awaiting the submission of requested documents from both Montenegro and Santos to proceed with the investigations.

The PGR indicated that the investigation involving Pedro Nuno Santos will be reassessed later this week, contingent upon the receipt of the requested documents.

Both Montenegro and Santos are currently under scrutiny as the PGR seeks to clarify the circumstances surrounding the property acquisition and the allegations against them.

Attorney General Amadeu Guerra acknowledged that the ongoing electoral campaign may influence the lack of document submissions, as individuals are not legally obligated to provide requested information.

Both investigations are being conducted by the Central Department of Investigation and Penal Action (DCIAP), which is responsible for managing these preventive inquiries.

The Spinumviva case has had significant political repercussions, including a failed motion of confidence presented by the government, which led to early elections on May 18, 2025.

On May 19, 2025, the PGR reiterated their need for responses to the requests made in relation to these ongoing investigations.

The PGR is currently awaiting responses to their requests for information related to both investigations, which are still in progress.
