Seven-time world champion Lewis Hamilton has said that the FIA's treatment of F1 Academy managing director Susie Wolff has been 'unacceptable' after a tumultuous week.
Wolff - and her husband Toto Wolff, Mercedes team principal - were claimed to be under investigation for an alleged conflict of interest due to their differing roles within the sport.
"A disappointing week really to see that the governing body of our sport has sought to question the integrity of one of the most incredible female leaders we've ever had in our sport, with Susie Wolff, without questioning, without any evidence," he told media.
"And then just saying sorry at the end, and that's just unacceptable.
"There is a constant fight to really improve diversity and inclusion within the industry. It seems there are certain individuals in the leadership within the FIA that, every time we try to make a step forward, they try to pull us back, and that has to change."
