Mikhail Prokhorov

Tens of thousands of Russians are expected to take to the streets on Saturday despite Kremlin efforts to ease tensions over disputed elections and Vladimir Putin’s expected return to the presidency. More than 50,000 people have indicated their intention to attend a protest on Moscow’s Sakharov Prospect, named after the late leading Soviet dissident Andrei Sakharov. Thousands more have signed up via social networking sites for protests in more than 80 Russian cities.

The protesters are hoping to capitalise on the momentum launched earlier this month, when up to 50,000 people turned out in Moscow alone demanding the Kremlin overturn parliamentary election results that saw Putin’s United Russia take a majority in the Duma despite widespread accusations of fraud.

The former Soviet premier Mikhail Gorbachev, the novelist Boris Akunin, the anti-corruption activist Alexey Navalny and Ksenia Sobchak, the Russian “It Girl” and daughter of Putin’s mentor, are among those expected to address the crowd. Protesters will don white ribbons to symbolise their opposition to the election results, which they say are a sign of their country’s lack of democracy. The oligarch Mikhail Prokhorov, who is running against Putin, also said he would address the rally.
