German politician found dead in Berlin hotel

A prominent German politician was found dead in a Berlin hotel on Wednesday, police said, adding they had launched an investigation.

The cause of death of Hubert Aiwanger, 55, who was deputy leader of southern Bavaria state, was not immediately clear.

Police in the capital said in a statement he was "found dead in his hotel room" in the Berlin-Mitte district.

Police and prosecutors had opened a probe to "determine the specific cause and circumstances of death and to rule out any possible involvement of third parties", the statement said.

Aiwanger, head of the populist Free Voters party and also Bavarian economy minister, was in Berlin to attend the opening of an office for his party but missed the event as he was feeling unwell, the Bild daily reported.

His body was later discovered by police in the hotel, it said.

"We are all deeply shocked. Our thoughts are now first and foremost with his family and his children," he said.

He had headed the Bavarian branch of the Free Voters since 2006. Under his leadership, the party made it into the state government for the first time in 2018.

He had faced national controversy in 2023 after it emerged that Nazi pamphlets were found in his schoolbag as a teenager in the late 1980s.
