The Paris judicial court rendered its judgment in the trial of the ultra-right group OAS on Tuesday.
He sentenced his leader Logan Nisin to nine years in prison.
This is a year less than the sentence requested by the prosecution last week after the trial of the 25-year-old accused of planning attacks against mosques as well as political figures.
Five other men, all former members of the OAS now aged 23 to 33, were also prosecuted in this case.
The justice accused the group of having planned terrorist attacks in order to "initiate" remigration "based on terror".
Their envisaged targets: Muslims, Arabs, black people… Or Christophe Castaner, then spokesperson for the Macronist government, and Jean-Luc Mélenchon, leader of rebellious France.
