Bob Bell is confident Renault will remain in Formula One despite the fall-out from the Singapore race-fixing scandal.

Former team principle Flavio Briatore and engineering chief Pat Symcox resigned over the affair before the former was hit with an indefinite ban from FIA-sanctioned motorsport and managing driver's affiliated with those series by the World Motor Sport Council.

The latter was given a five-year suspension by the same body after they were found guilty of conspiring with driver Nelson Piquet Jnr to fix last year's inaugural night race in eventual winner Fernando Alonso's favour.

Piquet deliberately crashed to bring out the safety car shortly after Alonso had pitted, allowing the Spaniard to climb the field while other drivers came in for fuel and tyres.

Following the damning verdict into the affair, there were fears the French motor company could pull out of the sport at the end of the season, particularly as two major sponsors had decided to terminate their relationship four races early, but Bell believes that will not prove to be the case.

"I'm not worried," he said.

"I think for me, the most important thing is that Renault are still here despite the crisis we've just been through.

"It's been an extremely deep and difficult crisis, not just for the team but for the parent organisation and the fact Renault have stood by us throughout all of this I think speaks volumes for their commitment both to the team and to Formula One because their commitments to motor sport, even beyond Formula One, are very broad and long-standing.

"So it's not a matter they take lightly but they have stood by us and I think that answers the question for you."

With Briatore's departure, Bell was handed the top job on a temporary basis but insisted he has no immediate desire to replace the flamboyant Italian on a more permanent basis.

"I have no intention of stepping into his shoes," he added.

"Housekeeping a few of his responsibilities over the coming months but I am no Flavio Briatore and I have no intention to be.

"It's extra work but not just for me, for a lot of people in the team. We are set up to deal with that and we are getting on with it. It has been a bit of a baptism of fire, back-to-back races on top of other things, so not much time to think about it.

"It's not a job I'm considering whether I do long term or not at the minute. I think Renault are probably in the same position. We need to get through these races in good shape and do some restructuring in the team and sort out some major issues in good time for next year."

One of those will be replacing Alonso, who is joining Ferrari at the end of the season.

"Fernando has been such a huge part of our team for many years. It is sad to see him go but we wish him well," said Bell.

"People move on at all levels of the sport and we will have to deal with it. I think it will work well for him there."
