Nielsen is present in the Bahrain paddock wearing an F1 shirt, although he does not have an official full-time title.
A former policeman, the highly respected Nielsen has been a familiar face in the F1 paddock since the 1980s.
Having started as a truck driver with the MSL catering firm, he worked for Team Lotus, Tyrrell, Benetton/Renault, Honda, Arrows, Caterham, Toro Rosso and Williams, mostly in team manager or sporting director roles.
He left Williams to join F1 as sporting director in August 2017, as one of the first key hirings made under Liberty Media’s ownership by Ross Brawn.
He had a wide brief at F1, getting involved in the development of the sporting regulations as well as having an operational role on race weekends.
He also worked closely with race venues around the world, and was a key player in the efforts to get F1 back on track during the COVID-19 pandemic.
