Johannesburg - Rightwing leader Andre Visagie was found guilty of illegal possession of firearms and ammunition, Beeld newspaper reported on Saturday.
His son, Jan, 18, who was his co-accused, was acquitted in the Kimberley Magistrate's Court in the Northern Cape on Friday.
Magistrate Vernon Smith said Visagie, leader of the Geloftevolk Republikeine, has “an absolute lack of trust” in the police and was also concerned about farm attacks, which made him believe people needed to be able to protect themselves.
Visagie had earlier told the court that a chest of arms discovered in his son's room had been planted there.
Smith found Visagie guilty but said there was no evidence that his son had knowledge of the firearms in the closet in his room.
A sentencing date is yet to be determined. - Sapa
