Kremlin-appointed mayor of Moscow Sergei Sobyanin looks set to secure another term after winning 57.7 of the votes, according to early exit polls.
The results come after only four percent of the votes have been counted. If he retains this lead, Sobyanin will not need a second round run-off for overall victory.
Sobyanin’s main challenger was the pro-democracy and anti-corruption campaigner Alexei Navalny.
Partial results show he has won 21.6 percent according to the RIA news agency. He has secured much support of late but his campaign team said their own early polls showed he had not crossed the threshold needed for a win.
