Formula 2 team Hitech GP have confirmed that they have terminated their partnership with sponsor Uralkali.
Hitech have been sponsored by the Russian potash fertiliser producer and exporter since 2016, the year in which Nikita Mazepin landed a drive with the team at F3 level.
Uralkali at one stage owned a share in the team, alongside two other companies, but, on 15 February, the team's founder, Oliver Oakes, seized control of all shares and thus regained complete ownership of the F2 outfit.
The decision was taken prior to Russia's invasion of Ukraine, with Oakes telling RacingNews365.com: "It was always part of the strategic plan for Bergton Management to exit Hitech in early 2022 and myself to own Hitech fully."
