Formula One's 10 teams are working with motor racing's governing body, the FIA, to find a long-term successor to race director Charlie Whiting.
Whiting died suddenly on Thursday morning aged 66 after suffering a pulmonary embolism, just three days before the season-opening Australian Grand Prix. His role was vital to the sport: as well as overseeing the FIA's operation of all on-track sessions, Whiting would oversee the start of every race and had a key role in dealing with safety and technical matters.
Whiting was a revered and respected figure in F1, having held the job since 1997 and been involved in the championship as far back as 1977 when he was a mechanic for the Hesketh team.
