🗣️ #RK88: "I would like to thank the team for the last two years and for helping make my comeback to the @F1 grid possible. I have enjoyed my time with ROKiT Williams Racing...but I feel that the time is now right for me to move on to the next chapter in my career.” pic.twitter.com/D7KdDovSFw
"It's a decision I took. I will see what opportunities are there for the future."
Kubica has recently been linked with a switch to DTM, but is also reported to have held talks with Racing Point ahead of a potential development role, having done similar for Williams before stepping up to the race line-up.
He added: "I always said that I took a lot of energy, a lot of time for me to come back to the sport.
"Since I joined Formula 1 [again] I said I would like to stay. I said this year would be a goal to remain in Formula 1.
"My answer is yes [I want to stay in F1] but not for every cost.
"I have to do what will bring me back a bit of joy in racing. This season has been very tough. Being back in Formula 1 after many years away is not easy, especially when we're in this situation, but I have to thank the team."
