The International Boxing Association (IBA) on Monday upped the ante in its battle for control of Olympic boxing by accusing the International Olympic Committee (IOC) of misuse of information about its officials.

In an open letter to IOC chief Thomas Bach and executive board members before their meeting in Lausanne on Tuesday, the IBA said it had "deep concerns" regarding basic IOC governance, impartiality and transparency principles during the monitoring process ahead of next year's Paris Olympics.

The IOC suspended the IBA in 2019 over governance, finance, refereeing and ethical issues and did not involve it in running the boxing events at the Tokyo Olympics. The IOC also plans to stage its own boxing qualifier for Paris.
