Russian opposition leader Alexei Navalny has been jailed for 15 days for resisting police orders during mass protests on Sunday.
Mr Navalny was one of hundreds of people who were detained across the country in connection with the rallies.
The court in Moscow earlier fined him the minimum 20,000 roubles ($350) for organising the banned protests.
Responding to the protests, the Kremlin accused the opposition of encouraging lawbreaking and provoking violence.
Some young people were paid to attend, a presidential spokesman said. Mr Navalny later repeated accusations of corruption against Prime Minister Dmitry Medvedev.
The allegations were the main reason behind Sunday’s protests, which drew thousands of demonstrators nationwide, including in St Petersburg, Vladivostok, Novosibirsk, Tomsk and several other cities, as well as Moscow.
