Robert Kubica will announce today that he won`t be Williams driver in 2020 season. It means that also PKN Orlen will leave Grove-based team. Pole and his management are searching for the best solution for 2020 season and it`s very likely that Kubica will be somehow connected with F1 and PKN Orlen will stay in series as well.
Those are unofficial news but I think they will be confirmed soon.
PKN Orlen was quite happy with financial and marketing results of backing Kubica and Williams but due to small chances for raising sporting level of Williams car, they decided leave the team and not fighting with Nicolas Latifi for 2020 seat.
