Robyn told BBC Sport: “During my tenure as CEO, I worked under challenging circumstances to strengthen the federation’s governance framework and upgrade its operational transparency.

“The resignation of the deputy president of sport clearly indicates there are serious ongoing structural challenges.

“When professional processes are not adhered to and stakeholders are excluded from decision-making, it undermines the foundation of a strong organisation.

“I am saddened to see these developments, as they threaten both the credibility and the long-term effectiveness of an important institution.”

Robyn’s comments are a direct reaction to the decision of Reid to resign on Thursday citing “a fundamental breakdown in governance standards within motorsport’s global governing body”.

Robyn added: “I worked closely with Robert during my time at the FIA and I have a great deal of respect for him and of course his commitment to the future of motorsport.”

Robyn left the FIA after raising questions about the general governance of the organisation and its professional practices, including finances in the president’s office.

Her departure was followed by those of the head of the audit committee Bertrand Badre and audit committee member Tom Purves, who were fired in the summer of 2024.

The compliance officer Paolo Basarri, who looked into the allegations that Ben Sulayem interfered in the operations of two races during the 2023 season, was fired in November.

The FIA has been approached for comment.
