Ralph Boschung has confirmed that he will be stepping away from the Formula 2 championship with immediate effect.
Boschung stated on social media post: "Unfortunately, I will not race any longer in Formula 2.
"It’s a shame that money is the major factor in this sport. I’ve been fighting so hard for so long. But expect me to fight back hard. I’m not giving up just yet. Thanks to everyone for the support. I really appreciate it. "
It is not yet clear who will replace Boschung at Trident and partner Giuliano Alesi for the remainder of the season.
Boschung has scored two top ten finishes this year, with a best result of ninth coming in Monaco.
MP Motorsport will also have a change to its roster, as IndyCar driver and Red Bull junior Patricio O'Ward steps in for the banned Mahaveer Raghunathan.
