The local Walloon government is not ruling out selling Spa-Francorchamps in order to secure the fabled circuit's future in F1.
Well-connected Belgian motor racing figure Bas Leinders this week suggested there is a serious buyer for the track, amid reports its race might have to annually alternate with a French venue in future.
Leinders referred to a "big investment company", and Belgian television RTBF suggested it might be Renault team owner Genii.
But the Luxembourg newspaper Wort said both Spa circuit boss Etienne Davignon and Genii have denied the rumours.
The Belga news agency also said Spa chief Pierre-Alain Thibaut played down the link with Genii's Gerard Lopez.
So too did Walloon government minister Jean-Claude Marcourt, but he admitted to La Libre newspaper that Spa-Francorchamps might be interested in linking up with a private investor.
He told La Derniere Heure: "I am open to any interesting initiatives, even though it is difficult to talk hypothetically.
"But I am interested so long as the private investor takes a substantial financial risk," he added.
