The ruling United Russia party, backed by Vladimir Putin, won the Parliamentary election with more than 54% of the votes.
He has now held power, either as a president or prime minister, for 17 years.
Early results on Sunday are reported to show Russia's ruling United Russia party winning in the parliamentary election amid allegations of election violations. "Not that they need it: The three other parties elected on Sunday support the president as well".
While voter turnout was lower, at 47%, the result otherwise represents a full 50% increase from five years ago, when United Russia won just over 50% of the Duma seats.
While casting his ballot, the leader of Russian opposition People's Freedom party or PARNAS Mikhail Kasyanov said he expected multiple cases of election fraud to be registered during the poll.
Zyuganov was outraged that LDPR could potentially beat his party in the vote, and accused United Russia of siding with LDPR to secure an absolute majority.
The head of the OSCE election monitoring team, Ilkka Kanerva, today said the vote was run more transparently than in the past, while noting issues such as restrictions on candidates, state control of the media, and numerous procedural irregularities, RFE reports.
The clip claims that it shows proof that the elections have been rigged after the United Russia party turned out on top.
The Communist party was in second place with 13.5 percent of the vote, followed by the Liberal Democrats party on 13.3 percent and the Just Russia party on 6.2 percent, according to an incomplete vote count.
"There is no question, we didn't get a good result in Berlin today", said Michael Grosse-Broemer, a senior CDU politician.
The comment by Central Electoral Commission head Ella Pamfilova was shorter: "The turnout was pretty standard", she said at a briefing.
The election for lawmakers comes 18 months ahead of the next presidential election.
Golos, an independent monitoring group, said it received nearly 700 complaints, such as ballot stuffing and multiple voting, including one in which a bus full of workers was seen at seven polling stations in Moscow.
"I think it is risky to transfer the Berlin result to the federal level", he told broadcaster ZDF.
The vote will be closely watched to see how many of Russia's roughly 110 million registered voters across its 11 time zones in what is the world's largest country turn up to cast their ballots, with some opinion polls showing apathy levels are high.
Pamfilova said other violations reports would be looked into and that results from three precincts could be annulled.
In the previous State Duma elections in December 2011, 19,000 out of 125,000 eligible Russian voters came to the polls in Estonia.
