Mark Walter might be unfamiliar in Formula 1, but for the Cadillac team, he holds fundamental relevance. The billionaire is the CEO of TWG, the company responsible for operating General Motors' Formula 1 entry, and currently he is under scrutiny by authorities in the United States which has sparked rumours regarding a potential sale of the team.
Recently, Walter sold his stake in the NBA's Los Angeles Lakers – just one year after acquiring it – while reports in the US have emerged that he is considering selling his shares in other sports ventures; including Premier League club Chelsea, MLB's Los Angeles Dodgers, and even Cadillac F1 and Andretti Global.
