Voters across Russia have been casting their ballots in dozens of local elections, seen as a big test for the ruling pro-Kremlin United Russia party.
Nearly 160,000 candidates are vying for seats in local parliaments. Governors are also being elected in many regions.
The polls come only weeks after the suspected poisoning of opposition leader Alexei Navalny with Novichok.
His team allege this was done on the orders of President Vladimir Putin – the Kremlin denies any involvement.
Mr Navalny had been backing key challengers to United Russia, which he describes as the “party of crooks and thieves”.
His team has been urging Russians to vote tactically to channel support towards candidates best placed to defeat United Russia.
In some places, these are people affiliated with Mr Navalny himself, while in other regions they are communist or nationalist challengers.
Mr Navalny’s camp believes this campaign could be why he was attacked, the BBC’s Sarah Rainsford in Moscow says.
She adds that United Russia has become increasingly unpopular, associated with a controversial pension reform, falling incomes – and corruption.
Russia’s electoral commission allowed early voting on 11-12 September because of the coronavirus outbreak.
But Sunday was the main day for tens of millions of voters across 11 time zones, with more than 56,000 polling stations prepared. Polls have now closed across the country.
They are also seen as a dry run for elections to the national parliament next year.
The authorities were then accused of a heavy-handed response to the rallies, which saw some of more than 1,000 people arrested receive sentences of up to four years in prison.
Early results from Russia’s Far East, where polling stations closed first, point to comfortable victories for pro-Kremlin candidates in at least two districts.
