MOSCOW, September 20 - RAPSI. The State Duma Commission for Control over the Credibility of State Deputies' Incomes and Expenses will hear cases on a number of lawmakers from the ruling United Russia party that are suspected by oppositionist A Just Russia party members of engaging in commercial activity, a violation on the law on lawmaker status.

According to current Russian legislation, deputies are not permitted to be involved in business.

Leader of A Just Russia Sergei Mironov submitted the inquiry to State Duma speaker Sergei Naryshkin. The list of suspects includes Vladimir Pekhtin, Andrei Knyshov, Elena Nikolaeva, Grigory Anikeyev, Sergei Esyakov and Ilya Kostunov.

Knyshov has already told RIA Novosti that he is ready to undergo an investigation into his activities; he said that he stopped running his business before he was elected an MP.

Head of the United Russia faction Andrey Vorobyov said that there is no information on the deputies in the inquiry which merits any attention, or any facts confirming that legislation has been violated.

He states that the State Duma does not hold special campaigns to strip certain MPs of their political power, the law applies to everyone equally.

Last Friday, the State Duma stripped A Just Russia party member Gennady Gudkov of his political power after the investigative authorities accused him of engaging in commercial activities.
