The Latest on Russia's parliamentary election (all times local):

9:05 p.m.

Russia's Central Election Commission says the very first results show the ruling United Russia party winning in the parliamentary election.

Polls closed at 9 p.m. local time (1800 GMT) in Russia's westernmost region while Russia's regions in the Far East and Siberia have been counting the ballots for several hours now.

Less than 7 percent of the ballots counted show United Russia getting about 44 percent of the vote, with the Liberal Democrat Party trailing behind with 18 percent of the vote. The results are likely to change as votes in the west of Russia are counted.

Complaints of election violations have been increasing as Russians vote for a new national parliament.

The voting for the 450 seats in the State Duma, the lower house of parliament, wasn't expected to substantially change the distribution of power, in which the pro-Kremlin United Russia party holds an absolute majority. But the perceived honesty of the election could be a critical factor in whether protests arise following the voting.

Massive demonstrations broke out in Moscow after the last Duma election in 2011, unsettling authorities with their size and persistence.

Russia's elections commission head says results from voting for parliament in a Siberian region could be annulled if allegations of vote fraud there are confirmed.

Ella Pamfilova's statement came Sunday as Russians cast ballots for the State Duma, the lower house of parliament.

The pro-Kremlin United Russia party is expected to retain its dominance and the three other largely cooperative parties in the current parliament are also expected to win seats.

Russian officials are concerned that widespread allegations of vote fraud could spark protests similar to the massive demonstrations after elections in 2011.

A candidate from the liberal Yabloko party in the Altai region of Siberia told state news agency Tass that young people were voting in the name of elderly people unlikely to come to polling stations.
