waving and chanting protesters called Saturday for a disputed parliamentary election to be rerun and an end to Vladimir Putin's rule, increasing pressure on the Russian leader as he tries to win back the presidency. The protesters shouted “Russia without Putin” and “New elections, New elections” as one speaker after another called for an end to Putin's 12-year domination of the country at the second big opposition rally in two weeks in central Moscow. “Do you want Putin to return to the presidency?” novelist Boris Akunin asked from a large stage. Whistling and jeering, protesters chanted: “No!” Witnesses said at least as many people turned out as at the last big Moscow rally on Dec. 10 to protest against alleged vote-rigging in the Dec. 4 election won by Putin's United Russia. Police said at least 28,000 attended the rally on Prospekt Sakharova (Sakharov Avenue), named after Soviet-era dissident Andrei Sakharov. But one of the organisers, liberal politician Vladimir Ryzhkov, put the crowd size at 120,000 people and some climbed lamp-posts or trees to get a better view. The big turnout is likely to encourage organisers to believe they can keep up the momentum of the biggest opposition demonstrations since Putin rose to power in 1999, although the prime minister seems intent on riding out the protests. “I see enough people to take the Kremlin and the White House (government headquarters) right now!” anti-corruption blogger Alexei Navalny, who has emerged as the most inspirational of the opposition leaders, said to loud cheers.
