Free Voters leader Hubert Aiwanger found dead in Berlin hotel at 55

Hubert Aiwanger, the leader of Germany’s conservative Free Voters party and Bavaria’s deputy premier, was found dead in a hotel room in central Berlin on November 4. He was 55. Berlin police confirmed his death in a joint police and prosecutors’ statement.

A preliminary autopsy announced November 5 found no evidence that another person was responsible for his death. Prosecutors said more forensic examinations were pending and the investigation remained open. Their statement did not identify a specific cause of death.

What investigators have established

Police said Aiwanger was discovered in the early evening in Berlin’s Mitte district. Prosecutors and a homicide team opened an inquiry. They sought to establish how he died and whether anyone else was involved. That assignment, described in the initial announcement, was not a finding that a crime had occurred.

The following morning’s autopsy supplied an initial answer on outside involvement, while leaving the medical explanation unresolved. This is an early finding. It does not establish a specific illness or give a final account of how he died. Further results had not been set out in the prosecutors’ update.

Aiwanger had been due to speak at the opening of his party’s Berlin office but withdrew for health reasons, according to dpa reporting carried by the Associated Press. That reported cancellation provides context for his visit; it does not establish the cause of death.

A long career in Bavarian politics

Aiwanger combined party leadership with a senior role in Bavaria’s government. He had headed the state’s economy ministry since November 2018, according to the ministry’s memorial page. His responsibilities covered economic affairs, regional development and energy. For separate coverage of the federal energy debate, see our report on the proposed electricity tax cut and its funding dispute. That federal proposal is distinct from the question of who takes over Bavaria’s ministry.

His political career began well before his appointment to government. A Bavarian parliament biography records that he joined the Free Voters in 2001, became its Bavarian chairman in March 2006 and entered the state parliament in October 2008. Born in Ergoldsbach on January 26, 1971, he trained as an agricultural engineer at Weihenstephan University of Applied Sciences.

The parliament’s biography also records a year of service in Germany’s armed forces from 1990 to 1991. His agricultural studies followed from 1991 to 1995. By the time of his death, his service in the state legislature had spanned more than eighteen years, while his time leading the economy ministry had lasted about eight years.

Those roles gave him a voice in his party and in state government. His death leaves the Free Voters facing a change in leadership. Bavaria has also lost a serving deputy premier and cabinet minister. The sources cited here do not establish permanent replacements for those posts.

Why his party matters in Bavaria

The Free Voters’ role is clearest in the state’s election results. In the October 8, 2023, Bavarian election, the party won 15.8% of valid combined first and second votes and 37 of the legislature’s 203 seats. The CSU won 37.0% and 85 seats. The official results put the Free Voters ahead of the AfD, which won 32 seats, and the Greens, which also won 32. The SPD won 17.

Together, the CSU and Free Voters emerged from that election with 122 seats, above the 102 needed for a majority in a 203-seat chamber. Those figures describe the election outcome, rather than a fresh audit of every lawmaker’s current affiliation. They explain why the smaller party was a central partner in forming the state government. Its support enabled a majority without requiring the CSU to govern with either the Greens or the SPD.

The Free Voters’ combined vote share rose from 11.6% in 2018 to 15.8% in 2023, a gain of 4.2 percentage points, according to Bavaria’s election results service. These are shares of valid combined votes. They are not percentages of all residents or all eligible voters. The results show the party’s progress under Aiwanger, but they cannot establish how much of that gain came from his personal appeal.

A regional strength that did not translate nationally

The party’s national record was much weaker. In the February 2025 federal election, the Free Voters took 1.5% of valid second votes, down from 2.4% in 2021, according to the Federal Returning Officer’s final results. Second votes determine parties’ proportional strength in the federal election system. Our guide to Germany’s elections explains the national system and government formation.

The contrast helps explain the different stakes of Aiwanger’s death. His party was an established governing force in Bavaria but had not reproduced its Bavarian vote share across Germany. A change at the top therefore affects both an existing state governing partnership and the party’s efforts to gain a larger national audience.

The two results are from different elections, held in different years and across different electorates. They should not be treated as a direct measure of voters changing their minds about Aiwanger. Nor do they provide a forecast of how the party will perform without him. That will depend on future leadership choices, candidates and events that these historical figures cannot settle.

The governing partnership he helped sustain

The CSU and Free Voters signed their current coalition agreement on October 26, 2023. The published agreement’s introduction describes a program for the 2023–2028 legislative term. Its themes include economic development, rural communities, technology, environmental protection and cooperation across urban and rural areas. Our Germany policy guide provides a broader framework for following the country’s policy disputes.

That document is evidence of the partners’ agreed priorities, not proof that they achieved each goal. It also shows that their relationship extended beyond the two leaders. A change in personnel does not, by itself, establish that the coalition agreement has ended or that either party has withdrawn from it.

At the time of the agreement, Free Voters parliamentary leader Florian Streibl presented it as a basis for practical government and continued cooperation with the CSU. His party’s announcement stressed that the document set out work for the following five years. That was the party’s case for the coalition, rather than an independent judgment of its performance.

The 2023 controversy remains part of his record

Aiwanger’s career also included a major dispute over an antisemitic leaflet from his school years. In 2023, he acknowledged that copies had been found in his schoolbag but denied writing the text. His brother took responsibility for its authorship, as described in the Central Council of Jews in Germany’s annual report. Authorship, possession and distribution are separate questions and should not be collapsed into a single claim.

Söder decided on September 3, 2023, to keep Aiwanger in office. He argued that dismissal would be disproportionate, citing the time that had passed, Aiwanger’s apology and the lack of proof that he had written or distributed the leaflet. Tagesschau’s contemporaneous account records that reasoning. It was a political decision about continued service in government, rather than a court ruling on every disputed detail.

Critics focused on both the leaflet’s content and Aiwanger’s response. In an August 27, 2023, statement, Central Council president Josef Schuster said the text degraded Holocaust victims and should not simply be dismissed as a youthful mistake. He also acknowledged that Aiwanger’s possible responsibility for its spread might never be fully clarified.

Schuster later criticized Aiwanger’s handling of the allegations and the delay before his apology. The council’s annual report preserves those concerns. The disagreement was therefore wider than a dispute over who typed the leaflet: it included the standards expected of a senior official confronting antisemitism and Germany’s Nazi past. These documented criticisms are part of Aiwanger’s political record. They provide no evidence about the circumstances of his death.

How Bavaria fills the government posts

Party leadership and public office follow different processes. Under Article 45 of Bavaria’s constitution, the premier appoints and dismisses state ministers with the state parliament’s consent. Article 46 provides that the premier chooses a deputy from among the state ministers, also with parliamentary consent. The full constitutional text sets out those separate roles.

That means the choice of a party leader does not automatically fill the deputy premiership or the economy portfolio. Those are government appointments subject to the constitutional process. The immediate questions are who will carry out the ministerial duties and whom the premier and parliament will approve for the posts. Naming a likely successor without a sourced announcement would go beyond the evidence available for this report.

Party tribute and official mourning

In its November 4 statement, the Bavarian Free Voters expressed shock and described Aiwanger as a leader who sought close contact with citizens and argued passionately for his convictions. The party said it would continue its work in his spirit. This was the party’s tribute to its leader, rather than an independent assessment of his record.

Bavarian premier Markus Söder ordered flags lowered at state government buildings on November 5, according to the state government’s announcement. For now, the central unresolved question is the medical cause of death, which authorities have not publicly specified in their preliminary findings.

This report draws on official announcements, election records and attributed reporting, following our editorial standards on sourcing and uncertainty. The investigation’s next findings may change what can be said about the death. The tributes and historical political disputes described above should be read separately from the forensic evidence. Neither supplies a medical explanation for what happened in the hotel room.
