Toro Rosso is not currently for sale, team boss Franz Tost insists.
Red Bull mogul Dietrich Mateschitz has in the past said he is prepared to sell the former Minardi squad, and it has been rumoured he is doubly keen now that Red Bull Racing cannot share technology with its junior team.
But Tost told motorsport-total.com: "My latest information from Mr Mateschitz is that he does not want to sell the team completely.
"He would have no problem if an investor came on board, but the majority would stay with Red Bull," the Austrian added.
