Navalny's team organized 90 protests across the country, dubbing them "He is not our czar", a reference to Putin, who was first elected president in 2000 and is already Russia's longest-serving leader since Joseph Stalin.

Pavel Kuznetsov, a 72-year-old pensioner wearing a T-shirt depicting Putin wearing a crown with a line through it, said he and others had turned up in Moscow to protest against what he said was an election created to keep a dictator in power.
Supporters of opposition figure Aleksei Navalny gathered for rallies across Russian Federation on Saturday.

With more than 56 million votes, nearly 77 percent of the total, his March election win was his biggest ever and the largest by any post-Soviet Russian leader, something he and his allies say gave him an unequivocal mandate to govern. "He has been doing it for 18 years and has done nothing good for it", said Moscow demonstrator Dmitry Nikitenko.
"Leaders who are secure in their own legitimacy don't arrest their peaceful opponents for protesting", she wrote.
Perhaps at the start of another six-year term for President Putin, is Mr Navalny not better served by focusing on his anti-corruption campaign which exposes the system for what it is, not for what he tries to make it seem?
