Seventeen deputies in the State Duma have been inactive during sessions for a year, according to an RBC report published Monday morning.

Analyzing the results of the past two Duma sessions, which ended in July, RBC found that 17 deputies did not submit a single bill, join their colleagues in any initiatives or speak up Duma session.

Chess grandmaster Anatoly Karpov, Arctic explorer Arthur Chilingarov and Adam Delimkhanov, a close associate of Chechnya’s leader Ramzan Kadyrov, were included on RBC’s list of “silent” deputies. All three represent the ruling United Russia party.

Last month, news agency Interfax reported that Duma Chairman Vyacheslav Volodin plans to crack down on absentee members, saying that the number of absentee deputies will be announced at the start of each plenary session.
