Russian prosecutors have demanded that an opposition activist be imprisoned for a total of 10 years on allegations of fraud.

In their closing arguments in a Moscow courthouse, prosecutors asked a judge to convict Alexei Navalny and imprison him for nine years, with an additional year added because of a prior conviction. The request for such a lengthy prison sentence is unusual for financial crimes in Russia.

Navalny, along with his brother Oleg, is on trial for allegedly defrauding a French cosmetics company in a criminal case in which no injured party has stepped forward. The prosecutors demanded that Navalny's brother be imprisoned for six years.

After becoming an online sensation with corruption investigations of Russia's elite, Navalny became one of the leaders of anti-government protests in 2012.
