MOSCOW, September 18. /TASS/. The public movement For Clean Elections has reported a possible vote buying in the city of Nizhny Novgorod in the middle reaches of the Volga River during elections to the Russian State Duma lower parliament house.

"For Clean Elections activists have videoed vote buying. Thus, representatives of an independent rating agency recorded voting by the voters they polled by means of receiving a certain card from them. The scheme was already tested at the elections to the City Duma [legislature] in 2015," the movement said in a press statement.

Activists have referred relevant claims to the police, the prosecutor’s office and the local election commission. "The police have already detained representatives of that organization," the statement said.

In general, according to the For Clean Elections observers who are working in 40 Russian regions, "the situation is calm, polling in proceeding in a regular mode."
