Spain's People's Party (PP) has formally requested access to a confidential Police National report that warned of a "high risk" of maritime irregular migration towards the Spanish mainland and the Balearic Islands.

The request comes after Prime Minister Pedro Sánchez confirmed the existence of the report during his appearance before Congress on September 3, in a statement that triggered a political dispute with the Balearic Government over what authorities knew, when they knew it and what measures were taken.

The PP is now seeking the full document, including its annexes and risk assessments, as well as communications showing how the warning was transmitted to central government security bodies and the Delegation of the Government in the Balearics.

PP Requests Full Police Report

The parliamentary request was formally registered on September 4 under reference C.DIP 124841 and is signed by seven PP deputies, including José Vicente Marí Bosó, Joan Mesquida Mayans and Carlos Simarro Vicens.

The deputies are requesting three main categories of documentation.

They want a complete copy of the Police National report, including all annexes and risk assessments.

They are also requesting copies of communications showing how the report was sent to the Ministry of the Interior, the Secretary of State for Security and the Government Delegation in the Balearic Islands.

Finally, they want documentation showing what measures were adopted following the warning, if any.

The request has been directed to the Ministry of the Interior, the Secretary of State for Security, the Directorate General of Police, the General Commissariat for Immigration and Borders and the National Immigration and Border Centre, known as CENIF.

Sánchez Confirmed the Report in Congress

The controversy began during Sánchez's appearance in Congress on September 3.

The prime minister was speaking primarily about the migration crisis in Ceuta and earlier warnings surrounding the situation there.

During his explanation, however, Sánchez confirmed the existence of a Police National report referring to a "high risk" but clarified that it did not concern the Ceuta border.

According to Sánchez, the report referred "exclusively" to maritime arrivals to mainland Spain and the Balearic Islands.

His clarification immediately shifted political attention towards the Balearics.

The statement was interpreted by the Balearic Government as evidence that security authorities had possessed advance information about a potential increase in arrivals to the islands.

Prohens Demands Explanations

Balearic President Marga Prohens reacted by demanding that the Spanish Government provide the reports and explain what measures had been taken.

The Balearic Government formally called for information about the alerts, the information available to central government and the response implemented after the warnings were received.

Prohens also questioned why she had not been informed during her meeting with Sánchez in Palma on July 29.

She has described the issue as one of institutional transparency and cooperation, arguing that information concerning potential risks to the islands should have been shared with the regional government.

Those statements are political allegations and have not established independently that information was deliberately withheld.

The Government Has Since Declassified Some Documents

The controversy gained another dimension on September 9, when the Spanish Government declassified documents relating to the wider crisis that had prompted Sánchez's appearance in Congress.

However, the documents made public contain only limited information specifically concerning the Balearics.

One of them is a July 23 report from the National Centre for Immigration and Borders, or CENIF, titled "Informe Inmigración Marítima Irregular".

That document records maritime arrivals between July 16 and July 22 and states that 3,723 migrants had arrived in the Balearic Islands by then aboard 195 boats. It recorded increases of 8% in arrivals and 9% in boats compared with the previous year.

The publication of that document has provided additional information about the scale and direction of maritime migration at the time, but it does not make the full confidential report sought by the PP publicly available.

A Separate CNI Assessment Also Mentioned the Balearics

A second document released in the declassification process was issued by Spain's National Intelligence Centre, or CNI, on July 27.

The document, titled "Punto de situación de la inmigración irregular hacia España a 30/06/2026", contained information covering mainland Spain, the Balearics and the Canary Islands.

It reported that 9,547 migrants had arrived in those areas by June 30, representing a 44% increase compared with the same period in 2025.

The assessment also identified Algeria as the only departure country at that point where flows were increasing, with 5,501 arrivals, 29% more than a year earlier.

The CNI document warned that continued migration towards Algeria and favourable summer navigation conditions could mean that the upward trend would continue.

It also noted that military operations in southern Libya could potentially contribute to increased migration into Algeria.

What the Public Documents Do Not Yet Show

The newly available documents provide useful information about migration flows, but they do not fully answer the political question now being raised.

The PP is specifically seeking the Police National report that Sánchez described as warning of a "high risk" of maritime arrivals to mainland Spain and the Balearics.

Its request covers the complete report, annexes, risk assessments and communications showing who received it.

The precise contents of that document, including the methodology behind its risk assessment and whether it contained specific warnings about particular islands such as Ibiza or Formentera, are not currently public.

PP Accuses Government of Passivity

The PP has used the dispute to intensify its criticism of the Spanish Government's handling of migration in the Balearics.

José Vicente Marí, the party's deputy spokesperson in Congress, accused the central government of "total passivity and inactivity" and argued that the increase in irregular arrivals should have triggered a stronger response.

The PP has also highlighted the number of arrivals recorded in recent years, although figures cited by the party are political claims and should not be treated as independently verified data without reference to the official migration statistics.

Marí has specifically criticised Secretary of State for Security Aina Calvo and Government Delegate in the Balearic Islands Alfonso Rodríguez, claiming that the response had largely consisted of temporary reception arrangements at ports.

Those accusations have been made by the PP and do not constitute established findings of wrongdoing.

The July Meeting Between Sánchez and Prohens

The political dispute is also centred on the meeting between Sánchez and Prohens in Palma on July 29.

Prohens says she was not informed of the warning during that meeting and argues that Sánchez instead indicated that irregular arrivals in the Balearics were expected to improve.

The Balearic Government subsequently requested an explanation of what information the central government possessed and what preventive action had been taken.

The Spanish Government has not publicly accepted the allegation that the report was deliberately withheld from the regional administration.

The question of what was communicated during the July meeting therefore remains part of the wider political dispute.

Migration Pressure on the Balearics

The controversy comes as the Balearic Islands continue to experience significant maritime migration, particularly through the route from Algeria.

The Ministry of the Interior's published migration statistics have documented substantial arrivals in the islands during 2026, with the western Mediterranean route remaining an important focus of concern.

For Ibiza and Formentera, the issue has become increasingly visible through the arrival of small boats, the use of emergency reception facilities and the broader pressure placed on local administrations.

Formentera has in particular faced growing demands on its child-protection and reception systems following arrivals involving unaccompanied minors.

The Human Cost Has Also Become a Major Issue

The debate is not limited to border management or political responsibility.

A number of deaths have also been recorded in connection with the maritime migration route affecting the Balearics.

The Balearic Government has repeatedly argued that the islands need greater national support because of the combination of arrivals, limited territory and pressure on local resources.

Prohens has called for increased resources for the State security forces and for Frontex to have a more permanent role in protecting and monitoring the islands' maritime borders.

The central government's assessment of those measures remains separate from the question of what the confidential Police report contained.

The Importance of the Risk Assessment

The political significance of the report lies partly in the wording used to describe it.

Sánchez confirmed that a Police National document referred to a "high risk", but the public does not yet have access to the full context of that assessment.

A risk warning can cover different scenarios and does not necessarily mean that authorities could predict the exact number, timing or location of future arrivals.

That distinction will be important if the document is eventually released.

The PP wants to establish precisely what the report predicted and whether the government's response matched the level of risk identified by police authorities.

A Request for Accountability and Transparency

The parliamentary request is therefore aimed at reconstructing the chain of information.

The PP wants to know when the report was produced, who received it, what risk it identified and what action followed.

It also wants to establish whether the Balearic Government was among the administrations that received the warning.

The questions are particularly important because the report was only revealed publicly during Sánchez's September 3 appearance, rather than through the normal publication of government migration statistics or reports.

The Debate Is Not Yet Resolved

The release of some documents on September 9 has provided additional context, but it has not ended the dispute.

The published CENIF report confirms that the Balearics were experiencing an increase in maritime arrivals by July, while the CNI document warned that conditions could sustain an upward trend.

But the specific Police National report referred to by Sánchez remains the central unanswered piece of the puzzle.

The PP wants that document released in full.

The Balearic Government is also seeking information and explanations from Madrid.

What Happens Next

The immediate next step is for the Spanish Government and the relevant security bodies to respond to the PP's parliamentary request.

It remains to be seen whether the requested Police National report can be disclosed in full, whether parts of it are classified or restricted for security reasons, or whether only certain sections can be provided.

Any response will be closely watched in the Balearics because it could clarify what information was available to Spanish authorities before the summer's migration pressure intensified.

It could also shed light on whether the warning referred to the Balearic Islands generally or contained more specific assessments concerning particular routes and islands.

Why Ibiza Is Paying Close Attention

For Ibiza and Formentera, the dispute matters because the maritime route in question directly affects the Pitiusas.

The islands have experienced repeated arrivals and increasing pressure on local administrations, while emergency and child-protection services have had to respond to the consequences.

Yet the exact relevance of the "high risk" warning to Ibiza remains unknown.

At present, the public evidence establishes that a Police National report existed and that Sánchez said it referred to maritime arrivals towards mainland Spain and the Balearics.

What it specifically predicted, what authorities did in response and whether the information was shared with the Balearic Government are questions that remain unresolved.

The PP's latest request now puts those questions formally before Congress.

Until the report itself is released or its contents are otherwise clarified, the political dispute will continue to revolve around a document that has been publicly acknowledged but whose full contents remain out of public view.
