An official friendship fuels a widening political crisis.
Lisbon | July 2026
Portugal’s Judicial Police have opened an investigation and referred the matter to public prosecutors after a trailer seized during a drug investigation was found being used by a company owned by a friend of Interior Minister Luís Neves.
The case has intensified political pressure on Neves, who led the Judicial Police before entering the Government of Prime Minister Luís Montenegro. Authorities are now seeking to determine how an item under police custody was transferred from the official storage system and ended up attached to a commercial vehicle belonging to Construbarcelos.
The trailer was confiscated in 2024 following the dismantling of an illegal drug-production laboratory. It was reportedly carrying containers of ammonia and should have remained in a facility designated for seized property in Seixal.
Portuguese media later located the equipment in Barcelos, attached to a truck operated by Construbarcelos. The company belongs to businessman João dos Santos Carvalho, who has a personal relationship with Neves and has also participated in renovation work at a property owned by the minister in Portugal’s Alentejo region.
The Judicial Police confirmed that the trailer had been found on the company’s premises. It was subsequently removed and returned, together with the products it contained, to the authorities’ custody.
The institution announced that it had immediately ordered an internal investigation to clarify the circumstances surrounding the transfer. The case was also reported to the Public Prosecutor’s Office because investigators believe the facts could potentially constitute criminal offences.
The incident has attracted additional attention because Neves served as national director of the Judicial Police from 2018 until his appointment as minister. The inquiry therefore raises questions about the management of seized assets, internal controls and the relationship between senior public officials and private contractors.
The controversy did not begin with the discovery of the trailer. Portuguese media previously reported that Construbarcelos had carried out work on several Judicial Police buildings worth approximately €1.9 million while Neves was directing the institution.
The same businessman was also responsible for renovation work at the minister’s rural property in the municipality of Odemira. That overlap between public contracts and private services has generated accusations of a possible conflict of interest and demands for a detailed explanation of the relationship.
Neves has denied participating directly in the selection of contractors for Judicial Police projects. He has argued that the national director does not intervene in the evaluation of companies competing for public contracts and only becomes involved during the final administrative stage of the process.
The minister has also said that he met the contractor in 2023, when most of the work commissioned by the Judicial Police had already been completed. Regarding the improvements to his private property, he described them as limited interventions that were paid as invoices were issued.
The Public Prosecutor’s Office had already been following information published about the case before the trailer was discovered. Prosecutors indicated that they could undertake any investigative measures considered necessary should sufficient grounds emerge.
Additional questions have since arisen over construction at the Odemira property. Reports have questioned whether a structure described as a water reservoir may instead function as a swimming pool requiring municipal authorization.
The Odemira municipal authorities announced that they would examine the legality of the structure and determine whether the work complied with local planning and licensing regulations.
Neves has also faced criticism for failing to include a company belonging to his wife in the declaration submitted when he entered the Government. Because the couple is married under a shared-property arrangement, the omission raised further questions regarding transparency requirements for public officials.
The minister acknowledged that the company had not been declared but characterized the omission as an oversight. The explanation has not ended the political controversy, which has expanded as new details about the minister’s personal and professional connections have emerged.
André Ventura, leader of the right-wing Chega party, has publicly demanded Neves’ resignation. He argued that the minister should leave the Government voluntarily rather than wait for the investigations and political pressure to intensify.
The controversy comes only months after Neves became minister of Internal Administration, the portfolio responsible for domestic security, policing, civil protection and emergency management. He entered office in February after the resignation of his predecessor, Maria Lúcia Amaral.
Amaral stepped down following criticism of the authorities’ response to Storm Kristin, which severely affected Portugal’s central coastline in January. Neves’ arrival was initially viewed as an unconventional appointment because he was not a senior party figure and came directly from the leadership of the Judicial Police.
His professional reputation had been associated with public communication and his position against automatically linking immigration with criminal activity. The current investigation, however, has shifted attention from his policing record to the integrity of institutional procedures under his former leadership.
No criminal responsibility has been established, and the investigation remains focused on clarifying how the seized trailer left official custody, who authorized or facilitated its movement and whether any public official or private party violated Portuguese law.
The political consequences will depend on whether investigators identify administrative negligence, unauthorized use of state property or evidence of preferential treatment involving the minister’s associate.
For Portugal’s Government, the case has become a test of transparency at a moment when public confidence depends not only on the minister’s explanations, but also on the independence and credibility of the institutions examining his conduct.
