The ethics committee for Formula 1's governing body has cleared Mohammed Ben Sulayem in a pair of whistleblower complaints that alleged the FIA president twice interfered in competition last year.

The FIA earlier this month said its compliance officer received two complaints against Ben Sulayem.

The first alleged he intervened to overturn a penalty given to Fernando Alonso at last year's Saudi Arabian Grand Prix. The second report from the same whistleblower also claimed Ben Sulayem told officials not to certify the Las Vegas circuit for its high-profile race last November.

"After reviewing the results of the inquiries, the Ethics Committee were unanimous in their determination that there was no evidence to substantiate allegations of interference of any kind involving the FIA President Mohammed Ben Sulayem," the committee said in its Wednesday ruling.

The ethics committee, which operates independently from the FIA, said it conducted a wide-ranging review that spanned 30 days with 11 witnesses interviewed.
