MOSCOW, October 9 - RAPSI. The State Duma Revenues Commission decided on Tuesday to review at its next meeting additional materials concerning United Russia deputies Grigory Anikeyev, Nikolai Bortsov, and Vladimir Pligin, which served as the basis for requests to investigate whether they are engaged in business activities.

The investigation was triggered by suspicions voiced by Yabloko leader Sergei Mitrokhin regarding some United Russia deputies. United Russia shared similar suspicions regarding A Just Russia deputy Gennady Gudkov.

The State Duma stripped Gudkov of his seat after the authorities accused him of engaging in business activities in breach of the law on state deputies.

In return, A Just Russia compiled incriminating evidence against members of United Russia.
