“Dear Mr. Pottakis, I urge you to provide assistance in overseeing the observance of the rights of the Russian citizen Alexander Vinnik,” Moskalkova said in a statement.

Vinnik has been detained for more than thirty months, which, according to the Russian Ombudsman, “casts serious doubt on” the implementation by the Greek authorities of the provisions of the European Convention on Human Rights, which guarantees the right to a fair trial within a reasonable time.

Moskalkova added that, according to media reports, Vinnik carries out a hunger strike for 28 days, and his right to a daily walk is violated. There are also reports of problems with the execution by the prison authorities of the right of a Russian citizen to legal assistance in isolation.

“As you know, Vinnik’s wife is seriously ill. Under all these circumstances, Vinnik’s psychological and physical condition is critical, ”he said.

Vinnik was detained in Athens in July 2017 at the request of the United States. He is accused of laundering up to $ 4 billion using a cryptocurrency exchange.

In December, in a conversation with RT, a Russian made a request to take care of his family - children and his wife.
