Alexei Navalny’s Anti-Corruption Foundation has published an investigation into property owned by Russian Prime Minister Dmitry Medvedev. The investigation refers to several estates in Russia and abroad.

According to the Foundation, Medvedev received one of his houses as a gift from entrepreneur Alisher Usmanov. Formally, the residence is listed as a charitable foundation.

The Foundation also claims that Medvedev supervises several charities which have received 70 billion rubles (approximately $1.2 billion; the precise period over the course of which this money was received was not specified). Foundation employees claim that this money originated from various sources and includes bribes from entrepreneurs Alisher Usmanov and Leonid Mikhelson, as well as revenue from Bashneft.

The Foundation also spoke of two yachts moored beside Medvedev’s residence in Plyos on Russia’s Volga River. The yachts are listed as belonging to an organization that is closely related to Medvedev.

According to the Foundation, Medvedev also owns a vineyard in Italy.
