Protesters are gathering for a rally in the Russian capital, with tens of thousands set to denounce parliamentary elections they say were rigged.
This latest show of strength in Moscow and events in other cities keep the pressure on Prime Minister Vladimir Putin, nearly three weeks after the poll.
The opposition says his United Russia party, which won a slim majority, benefited from widespread voting irregularities. They have dismissed Kremlin pledges of political change as too little too late.
As Putin prepares a return to the presidency, protest organisers say ex-Soviet leader Mikhail Gorbachev will be among those addressing the crowd’s today.
