Nikita Mazepin had his legal fight against sanctions imposed against him by the UK rejected by the High Court.
Mazepin and his oligarch father Dmitry were sanctioned in the wake of Russia's invasion of Ukraine in February last year. The latter is believed to have close ties to Vladimir Putin.
The European Union and Canada also imposed sanctions against the former Formula 1 driver. Mazepin issued a legal challenge against the UK's sanctions, which was dismissed by a High Court judge.
