Whiting, who carried out a wide range of duties as the FIA Formula One race director, died on Thursday from a pulmonary embolism in the southern Australian city where he was due to work this weekend.

News of the Briton’s death filtered through the paddock at Albert Park on the eve of Friday’s first practice session, with seminal figures from motorsport among those paying tribute.

Reigning world champion Lewis Hamilton said Whiting was an “iconic figure in the sport”.

He added: “What he did for the sport and his commitment, he really was a pillar.

“I’ve known Charlie since I started in 2007… what he did for the sport, his commitment, he really was an iconic figure.”

Four-time world champion Sebastian Vettel said he only spoke to Whiting on Wednesday.

He said: “You could ask anything at any time, his door was always open.

“He was a racer, he was just a very nice guy.”

Christian Horner, team principal at Red Bull Racing, said Whiting was a man with “great integrity” and “performed a difficult role in a balanced way”.
