The CSU member of the state parliament Martin Huber (44) will be the new general secretary of his party and thus the successor to the resigned Stephan Mayer.
Party leader Markus Söder announced this personnel decision on Friday in a switching conference of the CSU board.
Like Mayer, Huber comes from the conservative Upper Bavarian district of Altötting.
The CSU chairman Markus Söder justified Martin Huber's appointment as the new general secretary by saying that he now wants to "put his faith in Bayern".
It would be good if the Secretary General came from the parliamentary group, said Söder on Friday with a view to the state elections in autumn 2023.
"He burns, he wants it," he said of Huber.
"I trust you 100 percent, I also trust you to do that." Huber spoke of a great honor and a great task.
He wants to combine economy and ecology.
The CSU board had previously unanimously welcomed Söder's personnel proposal.
According to Söder, there were also suitable candidates in the Bavarian cabinet.
But he didn't want to create a gap in the cabinet.
Among others, Minister of Agriculture Michaela Kaniber and Digital Minister Judith Gerlach were traded for the post.
The previous CSU General Secretary Stephan Mayer surprisingly resigned on Tuesday evening.
After little more than two months in office, Stephan Mayer announced his resignation.
The 48-year-old named health reasons in a written statement.
At the same time, however, he admitted that, in retrospect, the choice of words was "possibly" inappropriate to a "Bunte" journalist.
The journalist had previously accused Mayer of threatening him over the phone in connection with a report on Mayer's private life.
Söder announced on Wednesday that he would quickly clarify the successor.
