Duke's late-January visit is being organized by Filip Vavra, who is associated with the neo-Nazi organization National Resistance, the Czech news agency CTK reported Tuesday.
Duke was expelled from the Czech Republic after police accused him of denying the Holocaust in his book, "My Awakening." Prosecution on the accusation was stopped before he was expelled.
"He has two reasons for his visit to the Czech Republic," Vavra was quoted by Tyden.cz as saying. "First, he will demand that the (Czech) state give him a satisfaction for the detention and accusation for which (he says) the police had no reason. Second, he has been embarrassed that about a half of the people who saw him in April are in prison."
During his last visit, Duke scheduled several lectures, but was detained before he could speak, supporters said.
Duke will "simply arrive" during his next visit, Vavra said, "and what will be happening, this is yet to be seen. He may again be detained, which would be only good because it will be (symbolic)."
