FIA president Mohammed Ben Sulayem allegedly told officials not to certify the Las Vegas Grand Prix circuit as safe ahead of the inaugural race late last year.
Now, it has been revealed to BBC Sport by an FIA whistleblower that Ben Sulayem allegedly told officials to find a way not to pass the circuit as safe for racing.
The BBC confirmed that this is the same whistleblower that told of potential race interference from Ben Sulayem during the 2023 Saudi Arabian GP, where he allegedly told stewards to overturn a penalty for Fernando Alonso.
Ben Sulayem allegedly involved in race interference
The claim has been made in a report by the FIA's compliance officer to the governing body's ethics committee, who Ben Sulayem has been referred to in an investigation surrounding the alleged race interference issue.
An official FIA spokesperson said in a statement: "From a sporting and safety perspective, the Las Vegas circuit approval followed FIA protocol in terms of inspection and certification.
"If you recall, there was a delay in the track being made available for inspection due to ongoing local organiser construction works."
As it happened, officials were not able to find any reason not to confirm the circuit as being safe, and therefore the race weekend went ahead, with Max Verstappen claiming victory last November.
