Johannesburg (CNN) -- The trial of two men accused of killing white supremacist leader Eugene Terreblanche is expected to start in the South African town of Ventersdorp on Monday.
Terreblanche, the leader of the neo-Nazi Afrikaner Weerstandsbeweging (Afrikaner Resistance Movement, or AWB), was killed in April following an apparent dispute over wages with workers on his farm.
Police have charged Chris Mahlangu, 29, and a 16-year-old in the death.
The trial was initially scheduled for December but was postponed several times as lawyers for the defendants changed.
Terreblanche, 69, was bludgeoned with clubs and stabbed with a machete during the attack at his farm near Ventersdorp in South Africa's North West province, police said.
The AWB is best known for trying to block South Africa's effort to end apartheid. The group used terrorist tactics in a bid to stall the country's first all-race vote in 1994, killing more than 20 people in a wave of bombings on the eve of the elections.
Terreblanche was convicted of a 1996 attempted murder of a black man who worked as a security guard on his farm. He served about two-thirds of a five-year sentence.
