Piquet senior raised concerns last year: report

LONDON: Formula One's governing body was made aware last year of allegations that Renault had fixed the Singapore Grand Prix by ordering Brazilian Nelson Piquet to crash, a British newspaper reported on Friday.

The Daily Mirror quoted the driver's father and namesake, also a triple world champion, telling investigators that he had spoken informally to FIA race director Charlie Whiting at the season-ending Brazilian race in November.

Piquet and Whiting worked together at the Brabham team in the 1980s, with the Briton acting as the champion's chief mechanic.
