Volkswagen Chief Executive Martin Winterkorn is set to become CEO of Porsche SE as well, two people familiar with the situation said on Thursday.

The supervisory boards of both German carmakers were poised to address the issue at separate meetings on Thursday, one of the sources said. Winterkorn would succeed Wendelin Wiedeking, who is departing from Porsche, VW's biggest shareholder.

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.
