Oscar Piastri has split from his management team, led by former Red Bull driver and nine-time Formula 1 winner Mark Webber and his partner Ann Webber.

Mark Webber started working with Piastri in 2019 before the latter made his Formula 1 debut in 2023 for McLaren after winning the Formula 3 and Formula 2 titles in consecutive seasons.

The news was confirmed after another disappointing weekend for Piastri where he finished sixth, 56 seconds behind team-mate and race-winner Lando Norris.

"I'd like to thank Mark and Ann for all their support and advice over the years," said Piastri, who is currently seventh in the F1 Drivers' Championship.

"Their guidance has been invaluable, particularly in navigating the beginning of my F1 career. I wish them all the best going forward."

Webber was key in Piastri's move to leave Alpine in 2022 to join McLaren after Alpine announced the Australian would drive for them in 2023.

Piastri rejected the announcement, leading to a dispute between himself and Alpine which led to a hearing at the FIA Contract Recognition Board (CRB).

The board ruled against Alpine and McLaren soon confirmed Piastri would replace the outgoing Daniel Ricciardo from 2023.

Webber, 50, had already taken a step back in his management of Piastri ahead of this season, attending fewer races.

"We are proud to have played a pivotal role in the formative years of Oscar's career and to have placed him in F1 so that he could compete at the front so early on," said Webber.

"Following our reduced trackside involvement this season, we have collectively agreed that now is an appropriate time to bring our management agreement to a close.

"This will allow Oscar to build on his achievements under a new management structure, and for us to embark on our new ventures. We wish Oscar all the very best for a long and successful career."
