Latest from our news desk on Volodymyr Zelenskyy:
Ukrainian actor Volodymyr Zelenskyy, who has said he is running for president of Ukraine, has admitted that he has commercial interests in Russia and has said he will divest himself of them "in the near future."
In an interview with Ukrainskaya Pravda on January 20, Zelenskyy confirmed a January 18 report by RFE/RL that he is a co-owner of a Cyprus-registered firm called Green Family LTD, which owns the Russian filmmaking company Grin Films.
