Vladimir Vasilyev, a deputy speaker of the Kremlin-controlled lower house, said Monday that he expects quick passage of the amnesty bill, but no date has been set for the vote.
Izvestia said that the amnesty also would apply to 30 crew members of a Greenpeace ship who were detained after their protest against a Russian oil drilling in the Arctic. They were granted bail last month pending trial after spending about two months in jail. They were initially charged with piracy, but investigators later changed the charge to hooliganism.
If the two jailed Pussy Riot members and the Greenpeace activists are pardoned under the amnesty, it could help dampen international criticism of the Kremlin ahead of the Winter Games in Sochi, which start in February.
Izvestia added the amnesty also could affect Russians facing charges for their role in a May 2012 violent protest in Moscow's Bolotnaya Square. The paper said seven of more than two dozen defendants could benefit from the amnesty.
Mikhail Fedotov, chairman of the Presidential Rights Council, confirmed that the Pussy Riot members, Greenpeace activists and some of the Bolotnaya defendants could fall under the amnesty, the ITAR-Tass reported.
Fedotov said opposition leader Alexei Navalny, who was convicted of embezzlement in a separate case and given a suspended sentence, would not fall under the amnesty. His conviction bars Navalny from running for political office for life.
