Paolo Basarri has left his position as the compliance officer of Formula 1’s governing body the FIA.
Multiple sources, both at and close to the FIA, said the Italian had been fired as a consequence of FIA president Mohammed Ben Sulayem losing confidence in him.
Basarri is said to have pushed back against or tried to navigate around a number of requests of Ben Sulayem, who took exception to that approach.
The FIA has declined to comment, while Basarri told BBC Sport: “I cannot comment on this.”
Basarri is the official who compiled a report into allegations that Ben Sulayem interfered in the operations of two races during the 2023 season.
A whistleblower told the FIA Ben Sulayem had intervened to overturn a penalty given to Aston Martin’s Fernando Alonso at the 2023 Saudi Arabian Grand Prix, and that he allegedly told officials not to certify the Las Vegas circuit for its race last year.
Ben Sulayem was cleared of the allegations following an investigation by the FIA ethics committee.
BBC Sport has been told Basarri left the organisation last week.
According to FIA rules, the compliance officer’s role is managed by the FIA Senate, which is required to give its permission if he is fired, but his position was not discussed at a meeting of the Senate this week, sources say.
Basarri is the second senior figure to leave the FIA in a week, following the departure of F1 race director Niels Wittich.
The FIA said Wittich had “stepped down”. The German told BBC Sport on Thursday: “I can confirm that I got fired and it was not my decision to leave F1.”
