Flavio Briatore has protested Renault's innocence after being accused by the FIA of having "unauthorised possession" of McLaren data.
In the second spy scandal to hit Formula One this year, Renault will have to appear before the World Motor Sport Council in Monaco on 6th December to answer the charges against them.
And although Briatore has conceded that Renault's recently suspended engineer Phil Mackereth "showed" some technical drawings of McLaren systems to his new colleagues at Renault, the team boss denies making use of the data.
"When we found out in September, we talked with this guy (Mackereth), we started an investigation and immediately suspended the guy and then immediately we informed McLaren and the FIA," Briatore told The Times.
"We gave to Mr (Max) Mosley all the correspondence and the evidence and a statement from our engineers making clear we never used any McLaren system in our car.
"The information was in the computer, it was in the disks that this guy brought. It was very simple. It was a drawing of a few systems, it was part of a drawing of the gearbox and was part of a drawing of a mass-damper.
"I am confident the information was not used and not only me. We have witness statements from every engineer that was involved and, categorically, everybody says that there was no influence of any of these things on the design of our car."
The Italian also revealed that at the time Renault invited 'independent experts appointed by McLaren (Kroll security firm) to visit their headquarters in Enstone, Oxfordshire, to investigate what had happened to Mackereth's data.'
However, he added the officials visit was a short one and that they simply took back the relevant disks.
"We were happy to let them inspect our computer, we wanted to give McLaren the opportunity to check that there was no influence on the design of our car, but they never took up the offer," he said.
The newspaper, though, reports that Briatore's account differs to that of the published versions 'which suggest that the Kroll team did examine the hard drives of the Renault computer system and that the dossier sent to the FIA by McLaren includes at least 15 statements from Renault engineers admitting that they had discussed the material brought by Mackereth.'
