Romanian far-right former presidential candidate Calin Georgescu has been charged with attempting to stage a coup after the first round of the presidential election was annulled last December.
Horatiu Potra, a former French legionnaire and militia chief in the Democratic Republic of Congo, and 20 other people were also charged.
The case rests on a planned raid on the Romanian capital Bucharest on 8 December, which police foiled.
Romanian prosecutors describe a plot targeting Romania's constitutional order, involving Georgescu, Potra, their group, and alleged foreign intelligence links.
Potra and others have been charged with instigating the coup, while Georgescu is accused of conspiring with Potra.
