Mikhail Gorbachev, the last Soviet leader, called Wednesday for new parliamentary elections in Russia over concerns about vote fraud.
"Mikhail Gorbachev is very concerned about how the situation in Russia is developing," spokesman Pavel Palezhchenko told CNN. "People don't believe that the will of the people is reflected in the results."
He confirmed a report by the Russian news agency Interfax, which quoted the former premier as saying the elections were unfair and new elections were needed.
Demonstrators have been protesting against what they describe as electoral fraud in Sunday's national vote, which kept Russian Prime Minister Vladimir Putin's party in power but significantly decreased the number of seats it holds in Parliament.
