Silverstone chief Richard Phillips and two other senior executives have been suspended.
Phillips, who has been managing director of Silverstone Circuits Ltd (SCL) since 2004, will receive full pay while an internal investigation is launched.
The company’s financial director, Ed Brookes, and legal director, David Thompson, have also been suspended.
Chairman of the British Racing Drivers’ Club John Grant and Lawrence Tomlinson, the club’s director, have assumed the role of joint acting chief executive of the circuit.
The club, which owns the circuit-managing company, said it is taking ‘a closer role’ in the running of the business, with a ‘new operating structure between the club and the circuit’.
A spokseman from the club said: “Whilst we cannot comment on the suspension of senior executives at SCL, it should be noted that this is only coincidental to the restructure.
“Having reviewed the Silverstone business, we have embarked on an exciting programme of restructuring to make the business more streamlined, concentrating on their core competencies as a circuit operator and the home of the British Grand Prix.”
