The National Bolshevik Organisation in Russia remains banned. Russia's Supreme Court has upheld an earlier decision by a Moscow city court, against which the group was appealing.

It defines the National Bolshevik organisation as extremist and prohibits its activities.

The court's decision comes into force on Tuesday.

The National Bolsheviks Party, as it was called before being banned in 2005, was often accused of using Nazi ideology, and their quite confusing slogans mix youth, Stalin and monarchy. Eduard Limonov is the founder and the head of the radical leftist organisation. His many books reflect the group's ideology and programme, like depriving pensioners of their voting right, limiting education to five years and taking children away from parents to be raised in foster schools.
