Other mourners lay flowers as police maintain presence at cemetery where opposition leader was buried
The mother of the Russian opposition leader Alexei Navalny has visited his grave, a day after thousands of Russians risked arrest to pay tribute to the anti-corruption campaigner at his funeral.
Navalny, who was Vladimir Putin’s fiercest critic for more than a decade, died last month in a prison colony where he was serving a 19-year sentence for “extremism” charges largely regarded as retribution for his opposition to the Kremlin.
