May 11 (GMM) Red Bull team boss Christian Horner has fuelled speculation that Renault's future in formula one is far from secure.

"We don't know that for sure at the moment."Renault is set to lose the title backing of the struggling Dutch bank ING at the end of the year, but boss Flavio Briatore insists the situation is no worse for Renault amid the economic crisis than it is for any of its rivals.And he told Spain's Sport newspaper: "I've been to the president of Renault in Paris and he confirmed to me that F1 is a priority for the group."
