Robyn told BBC Sport:
“The resignation of the Vice President of Sports clearly shows that there are serious, continuing structural challenges.
“If professional processes are not adhered to and stakeholders are removed from decision-making, the foundation of a strong organization is hampered.
“We are saddened to see these developments because they threaten both the reliability and long-term effectiveness of key institutions.”
Robin’s comments are a direct response to Reid’s decision to step down on Thursday, citing “a fundamental breakdown of governance standards within the global governance body of motorsport.”
Robin added: “I have worked closely with Robert during my time at the FIA and I have great respect for him and of course my commitment to the future of motorsport.”
Robin left the FIA after raising questions about the organization’s general governance and its professional practices, including finances in the president’s office.
Her departure was followed by the head of the Audit Committee Bertrand Budre, who was fired in the summer of 2024, and Tom Parks, a member of the Audit Committee.
Compliance Officer Paolo Basari investigated allegations that Ben Slyem had interfered with the operation of two races during the 2023 season, but was fired in November.
The FIA was approached for comments.
Reid’s resignation comes after Motorsportuk Chairman David Richards wrote an open letter to members of the organization accusing the FIA of being a “moral compass shift.”
The controversy caught up in Ben Slayem includes his views on women, his approach to Formula One, the firing of many seniors amid questions about the president’s office’s finances, changes to rules regarding public conduct for Formula One drivers, and allegations of interference in Grands Prix since the FAI rejected it.
The FIA is also being sued by Susie Wolff, director of young female drivers at the F1 Academy and wife of Mercedes F1 boss Toto Wolff.
