Lower house of parliament approves two bills, which must now be signed by President Putin, seeking to end European court's jurisdiction in the country.
The extension in sentence came after Alexey Navalny was found guilty of additional embezzlement and contempt of court charges.
Russian President Vladimir Putin has kept a few officials close during his lengthy rule over the country.
Opposition leaders have decried the elections as one-sided, especially under a system favouring the ruling United Russia party, which has won two-thirds of the seats in the parliamentary elections.
The election, marred by numerous reports of violations, lacked significant opposition presence after authorities declared organisations linked to imprisoned Alexey Navalny, the Kremlin’s most prominent foe, to be extremist.
While Russian President Putin remains popular, United Russia party has seen its support drop as living standards decline following years of economic stagnation.
Moscow court outlaws organisations headed by jailed Kremlin critic Alexey Navalny as "extremist", rendering their staff liable to criminal prosecution.
President Vladimir Putin signs legislation that bars members of "extremist" organisations from running for office, a decision allies of jailed Kremlin critic Alexey Navalny say aims to sideline them from parliamentary election this year.
The bill will make it impossible to run in elections for leaders, sponsors and rank-and-file members of “extremist” organisations, a designation being considered for opposition leader Alexey Navalny’s political network.
The draft legislation would affect not only senior members and activists of Kremlin critic Alexey Navalny's political network but also tens of thousands of Russians who supported its work with donations.
The Russian Foreign Ministry has accused the EU of trying to punish Moscow for its “independent foreign and domestic policies” and of trying to contain its development with “unlawful restrictions.”
Russia’s financial monitoring agency says it added jailed Alexey Navalny’s political network to a list of organisations involved in “terrorism and extremism” as a court considers also adding Kremlin critic’s Anti-Corruption Foundation.
