Nikita Mazepin says he will sue Haas for unpaid salary from this season as he continues his feud with the team following his sacking in March.
The Russian racer was dismissed by the team in the wake of his country's invasion of Ukraine. Title sponsor Uralkali, owned by his oligarch father Dmitry, was also cut loose with team chief Guenther Steiner later explaining that the situation was "untenable".
Days earlier, Mazepin and all other Russian racers were banned from competing on UK soil, excluding him from the British Grand Prix at Silverstone despite the fact the FIA had cleared him to race in 2022. In the wake of his sacking, Mazepin and his father were slapped with sanctions by the EU for their ties to Vladimir Putin.
