Sponsorship guru Zak Brown will step down from his role as group CEO of CSM Sport & Entertainment at the end of the year, amid growing speculation that he will be drafted in for a commercial role with new F1 owners Liberty Media.
Brown, the founder of the the world's largest motorsport marketing agency JMI, will continue his involvement with CSM as chairman of the Global Advisory Board and non-executive chairman of JMI, which was acquired by CSM.
He will be replaced by Chris Satterthwaite, the CEO of Chime Communications.
Brown has been one of the men linked to a commercial role with Liberty Media, which announced a $8.5 billion deal to purchase F1 earlier this month.
His decision to step down from CSM frees him up for a possible role in F1.
"I feel privileged to have been part of an extraordinary team during my tenure," Brown said. "I'm satisfied that we have achieved what I set out to do, from the successful integration of JMI into CSM through to preparing a strong business for a successful future."
"I would like to thank both Chris Satterthwaite and CSM Chairman Lord Coe for their invaluable support and commitment, without which these accomplishments and many more would not have been possible.
"I will take this experience forward to my next chapter in the arena I know best, motorsport."
