Umar Nazarovich Kremlev

The IOC has been concerned about the IBA under Kremlev's leadership. Kremlev has ties to Vladimir Putin, has moved much of IBA's operations from Lausanne, Switzerland to Russia, has spent heavily on apparent self-promotion, and has opposed independent appointment of judges and referees. The IOC has also been alarmed by the fact that the IBA's only sponsor is a Russian company that supports the Russian invasion of Ukraine. In September 2022, IBA voted against a presidential election, cementing Kremlev's position as the organization's president.

He won a vote of 57.33 per cent to replace Mohamed Moustahsane of Morocco to serve as AIBA's President, on 12 December 2020. The election was held virtually at AIBA’s ongoing congress due to the COVID-19 pandemic. It was attended by 155 National Federations from five continents.
