STUTTGART (Reuters) -- Volkswagen AG CEO Martin Winterkorn is set to also become CEO of Porsche Automobil Holding SE, two people familiar with the matter said.
One source said that Winterkorn wants to "assume responsibility" at Porsche SE, which owns the Porsche sports car company and holds Porsche's 51 percent stake in VW.
The holding company was forced by debt troubles to abandon efforts to seize full control of Europe's biggest carmaker.
The supervisory boards of both German carmakers were poised to address the issue at separate meetings on Thursday, one of the sources said.
Volkswagen's supervisory board is also set to approve the purchase of a minority stake in family-owned Porsche SE's healthy sports car business, Porsche AG, as a first step in integrating the two German carmakers.
At Porsche SE, Winterkorn would succeed Wendelin Wiedeking, who was CEO of the holding company and Porsche AG but departed after losing a power struggle with VW.
Wiedeking's post as the head of Porsche AG was filled last month by Michael Macht.
Two VW supervisory board members told Reuters on Wednesday that Volkswagen and Porsche had broadly agreed on details for a deal to combine two of Europe's most storied automakers.
Volkswagen is set to buy a stake of up to 49 percent in Porsche AG in a first step toward creating an "integrated" automotive group by the end of 2011.
Analysts value Porsche's sports car business, which makes the famed 911 models, between 8 billion and 11 billion euros ($11.4 billion and $15.7 billion).
