Ecclestone wants Mosley to stay
Mosley, 69, is contemplating whether to renew his tenure beyond next October, and F1 chief executive Ecclestone said: "I would re-elect him for another two decades.
"If he wants to stay, it's right that he should," the Briton told La Gazzetta dello Sport.
In the wide-ranging interview, Ecclestone also played down suggestions the night racing concept might be set to spread beyond the inaugural Singapore grand prix.
"It is limited to Asian and overseas races," he said. "Theoretically all the grands prix in that part of the world could be at night, but in 2009 there will only be Singapore."
Ecclestone also said he would be happy to see MotoGP's Valentino Rossi switch to F1.
Asked how much he would like to see it happen, the billionaire answered: "Very. I hope he will arrive one day, and Ferrari give him the machine to do it."
