With 31 percent of the votes counted, mostly in eastern part of the country, Vladimir Putin leads with 73 percent of the vote, well above the simple majority needed to avoid a run-off.
First-time Communist Party candidate Pavel Grudinin is running second with 15 percent, while veteran nationalist politician Vladimir Zhirinovsky, who first ran against Boris Yeltsin in 1991, rounds out the top three with about seven percent.
None of the other five candidates is on track to receive more than two percent of the vote.
The early results are in line with exit-polls conducted by Russian polling agencies FOM, which predicted Putin would take 77 percent of the vote, and VCIOM, which forecast a final share of 73.9 percent for the current president.
Ella Pamfilova, head of the Russian Central Election Commission, has said that there were no major violations during the vote, and that only “minor and local complaints” were received.
Vladimir Putin is widely expected to address his supporters at a massive anniversary rally in Moscow’s Red Square, dedicated to Crimea voting to become a part of Russia four years ago.
Putin was first elected to the Kremlin in 2000, and again four years later. Constitutionally barred from serving more than two consecutive terms, he did not run in 2008, the same year presidential terms were extended from four years to six years. Putin won 63.6 percent of the vote in 2012, and, if the early results are confirmed, he will now stay in his post until 2024, the year he turns 72.
