Vladimir Putin stormed to victory in Russia's presidential election, giving him another six years in power as Moscow's relations with the West plunge to new Cold War lows.
Putin, who has ruled Russia for almost two decades, won more than 75% of the vote according to preliminary results, but the opposition cried foul.
It reported ballot stuffing and other cases of alleged fraud as the Kremlin pushed for high turnout to give greater legitimacy to Putin's historic fourth term.
The Russian strongman ran against seven other candidates, but his most vocal critic Alexei Navalny was barred from the ballot for legal reasons and the final outcome was never in doubt.
"I see in this (result) the confidence and hope of our people," Putin said in an address to crowds of supporters on a square next to the Kremlin after exit polls put him on track for a resounding victory.
"Our thoughts will turn to the future of our great country and the future of our children," said the man who is already Russia's longest-serving leader since Stalin.
About 107 million Russians were eligible to cast ballots and the central election commission said turnout was 60 per cent three hours before polls closed in Moscow, after the authorities used both the carrot and the stick to boost participation.
Selfie competitions, giveaways, food festivals and children's entertainers were laid on at polling booths in a bid to create a festive atmosphere around the election.
But employees of state and private companies reported coming under pressure to vote, while students were threatened with problems in their exams or even expulsion if they did not take part, according to the opposition-leaning Novaya Gazeta newspaper.
According to central election commission data with half of votes counted, Putin took 75 percent of the vote, well ahead of his nearest competitor Communist Party candidate Pavel Grudinin at 13.2 per cent.
Results for all other candidates, including former reality TV host Ksenia Sobchak and ultra-nationalist firebrand Vladimir Zhirinovsky were forecast to be in single figures.
The election came with Russia facing increasing isolation on the world stage over a spy poisoning in Britain and a fresh round of US sanctions.
Navalny -- who called on his supporters to boycott the "fake" vote and sent over 33,000 observers across the country to see how official turnout figures differed from those of monitors -- said there had been "unprecedented violations".
His lawyer Ivan Zhdanov said the actual national turnout at 1700 GMT, when polls closed in Moscow, was 55 per cent, according to data collected by monitors.
Navalny's opposition movement and the non-governmental election monitor Golos reported ballot stuffing, repeat voting and Putin supporters being bussed into polling stations en masse.
One election commission worker in the republic of Dagestan, which traditionally registers extremely high official turnout figures, told AFP around 50 men entered the station where he was working and physically assaulted an observer before stuffing a ballot box.
But the electoral commission dismissed most concerns, saying monitors sometimes misinterpret what they see.
Since first being elected president in 2000, Putin has stamped his total authority on the world's biggest country, muzzling opposition, putting television under state control and reasserting Moscow's standing abroad.
The 65-year-old former KGB officer used an otherwise lacklustre presidential campaign to emphasise Russia's role as a major world power, boasting of its "invincible" new nuclear weapons in a pre-election speech.
Most people who spoke to AFP said they voted for Putin, praising him for restoring stability and national pride after the humiliating collapse of the USSR.
"Of course I'm for Putin, he's a leader," said Olga Matyunina, a 65-year-old retired economist.
"After he brought Crimea back, he became a hero to me."
Sunday marked four years since Putin signed a treaty declaring Crimea to be part of Russia in a move that triggered a pro-Kremlin insurgency in east Ukraine, a conflict that has claimed over 10,000 lives.
