MOSCOW—Russia's central bank revoked the license of a medium-size Moscow-based lender, notable for the presence on its board of a cousin of President Vladimir Putin, for alleged false accounting and repeated violations of anti-money-laundering laws.
The closure of Master Bank is the highest-profile move to date by the central bank since its first female governor, Elvira Nabiullina, took the helm in July, and could herald a new push in Russia's chronic struggle with money-laundering.
Igor Putin, a cousin of President Vladimir Putin, is still on the board having previously served as a vice president for a brief period. The Kremlin's press office said it couldn't immediately respond to a request for comment.


Если вкратце, то вроде как в правлении банка был двоюрный брат Путина.
