Last month, Russian billionaire Mikhail Prokorov's Onexim group sold 18.5 percent of Polyus to retail tycoon Zelimkhan Mutsoyev for $1.77 billion (1.17 billion pounds) and 19.28 percent to fruit juice magnate Gavriil Yushvayev for $1.85 billion.

Razumov was a non-executive director nominated by Onexim while Mosionzhik was a representative of Nafta, the investment vehicle of tycoon Suleiman Kerimov that owns 40 percent of Polyus.
