Bernie Ecclestone has reiterated that "things are sorted" in terms of Red Bull's Formula 1 future.
Red Bull and Toro Rosso are without an engine supplier for the 2016 season after a messy end to their relationship with Renault. They initially turned to Mercedes and Ferrari, but the former said no while the latter is apparently only prepared to give them 2015-spec engines.
The powers that be at Red Bull, though, want engine parity with the factory teams and have threatened to pull out of the sport, adding that their rivals are "afraid" of powering them.
However, the latest reports claim they are back in negotiations with Renault and Ecclestone, who admits that he was worried Red Bull would leave, insists the issue has been resolved.
Asked if he thought Red Bull would pull out, he told Autosport: "I think now, with what's happened, no.
"But before, I thought yes."
He added: "Things are sorted."
