Whitmarsh sure Resource Restriction Agreement can be a success

In Singapore, Red Bull Racing was forced to once again deny that it breached the RRA spending limit last year en route to the world championship on the back of an investigation by Dutch consultancy firm Capgemini.

And while there remains issues in the RRA that teams are working to overcome, Whitmarsh said on Saturday that he remained confident that the document can be made to work.

He also made it clear that there was no evidence that any team in F1 had exceeded the spending limits laid down in the RRA.

"We are operating to the agreement that we signed last year," he said. "The nature of F1 is that there will be accusations, claims and concerns, but there is no evidence that anyone has shown me of any team in breach of RRA.

"I think it is a bit like technical regulations, there will be finger-pointing, suspicion, paranoia - that is the nature, and the sometimes corrosive nature of this paddock, but I think the RRA has achieved an enormous amount.

"Without it, there are teams today that would not be here. It has clearly saved a lot of money in our sport. It is very evident certainly in this team when you hear conversations about efficiency, how you get the best out of the finite resource, people, wind-tunnel time, CFD, testing, the number of people we have at the track; those are all real and tangible."

He added: "It has achieved a lot. It is not perfect, but I am sure there will always be some more adventurous interpretations and people will look for opportunity, and we have to work hard to make it work."
