Russians residing in the country's easternmost regions of Kamchatka and Chukotka began casting votes on Sunday to elect the next Russian president.
The polling began at 8 am (Russian time) from far-east region of Vladivostok and will conclude at 8 pm in Kaliningrad, the Baltic exclave that is Russia's westernmost region.
At least 111 million Russian citizens are expected to cast votes to choose the country's president for the next six years, Sputnik reported.
Russian nationals are electing the country's head of the state among eight contenders - Sergey Baburin from the All-People's Union party; Communist Party candidate Pavel Grudinin; incumbent Russian President Vladimir Putin; Civil Initiative party candidate Ksenia Sobchak; Communists of Russia party chairman Maxim Suraykin; Presidential Commissioner for Entrepreneurs' Rights Boris Titov; co-founder of the Yabloko party Grigory Yavlinsky, and head of the Liberal Democratic Party of Russia Vladimir Zhirinovsky.
The number of eligible voters in Russia equals 108.9 million people as of January 1, 2018, while abroad, the number exceeds 1.87 million people.
Putin's victory in Russia's presidential election isn't in doubt. The only real question is whether voters will turn out in big enough numbers to hand him a convincing mandate for his fourth term - and many Russian workers are facing intense pressure to do so.
Earlier, the Russian Central Election Commission (CEC) carefully checked the number of voters in order to cleanse the voter lists of phantom voters and repeated mentioning of voters, Sputnik reported.
It also cooperated with the Russian Interior Ministry to rule out the double reporting of those who permanently reside abroad being registered in Russia.
The CEC has significantly simplified the voting procedure at the place of one's factual residence.
The residents of Moscow who decided to cast their votes for a presidential candidate and vote on the address of permanent residence registration may choose the most convenient polling station among 3,605 ones, only taking their passports along with.
Those who vote in the Russian capital but are not registered there had to apply until March 12 to any local election commission, multi-service centre or online state services portal, in order to be allowed to vote at a place of residence.
The results will be announced on March 19.
