Formula One's governing body approved statute changes on Friday that critics say will limit the powers of audit and ethics committees. The International Automobile Federation (FIA) said the revisions were approved at its general assembly in Kigali ahead of a gala awards ceremony for the year's various championships in the Rwandan capital. Motorsport UK head David Richards has voiced concern about a move that hands FIA president Mohammed Ben Sulayem and senate president Carmelo Sanz de Barros oversight of any ethics complaints. The head of Austria's motorsport federation Oliver Schmerold also told the BBC that the changes would reduce accountability at the FIA and were "not good governance". The FIA, also the governing body for rallying and electric Formula E, said in a statement the ethics committee will retain its independence and had the powers to assess independently whether or not to launch an investigation.
