Formula One's governing body was first told about Renault's race-fixing last year, according to the father of the driver at the centre of the scandal.
Nelson Piquet Sr has claimed that he first informed the FIA about the Singapore Grand Prix race fix claims at last year's season-ending race in Brazil - but was told that no action could be taken until his son made an official statement about the matter.
British newspaper The Daily Mirror published extracts of an interview that Piquet S. conducted with Martin Smith of investigators Quest on 17 August this year, where he talked about bringing the matter to light.
"When this thing happened in Singapore I couldn't believe it. I'd done motor racing for all my life," Piquet is quoted as saying.
"I couldn't believe this thing. And after I called Nelson, and Nelson said yes they asked me if I could help and this and that. I said 'but you could have hurt yourself and if you didn't hurt yourself you could have hurt somebody else' and he said 'yeah, I know it's wrong' but anyway.
