Two exit polls have indicated Kremlin favourite Sergei Sobyanin was on track to win the Moscow mayoral election with about 53 per cent of the vote, according to state-run RIA and Itar-Tass news agencies.
But opposition candidate Alexei Navalny has disputed the results.
Sobyanin, the Kremlin-appointed acting mayor, needed at least 50 per cent to win the election outright and avoid a runoff. Navalny's campaign said its own exit polls showed Sobyanin received 46 per cent and Navalny 29 per cent.
Mo Farah is expecting to get Great Britain's World Championships off to a golden start in Russia today.
A year on from taking the 5,000 and 10,000 metres titles at London 2012, he is hoping to repeat the feat in Moscow.
First up is the 10,000m final at the Luzhniki this evening - his first race on the track at this distance since last year's Olympic final.
Farah took silver over that distance at the World Championships in Daegu two years ago, but UK Athletics performance director Neil Black is confident he can go one better today.
"His expectation is higher than anyone else's," he told Press Association Sport.
"He will, without doubt, expect to win. It will take an amazing performance for that not to happen so we will find out tomorrow what happens."
Chinese President Xi Jinping's first state visit to Russia has been given a boost by his wife Peng Liyuan, who featured extensively in Sunday's state media reports on the trip.
China's first ladies are usually kept out of the public eye and not given notable media coverage, but Liyuan is famous in her own right in the country as a folk singer and television star.
Her glamorous image and confident media presence has invited comparisons to French former first lady Carla Bruni.
The 50-year-old is the first high-profile leader's wife in more than half a century, since the late actress Jiang Qing, who was married to Chairman Mao Zedong.
Given China's famously secretive Communist leadership, Liyuan's presence is widely seen as a positive addition to the party.
