Breivik will be given two hours to make his own case as to why he should be released.
He has called Par Oberg, a leading Swedish neo-Nazi, to testify for him at the parole hearing.
Oberg, one of the leading figures in the militant neo-Nazi Nordic Resistance Movement, was last year found guilty of committing hate crimes after he was recorded on film chanting “Hell Seger!”, the Swedish version of the Nazi slogan “Sieg Heil!”
If Breivik’s request for release is denied, he can apply for a new probation hearing in a year’s time, Ms Karlsdottir said.
Breivik’s re-emergence in the public eye five years after his last court case is painful for the friends and relatives of the people he killed, particularly as his parole requests are now likely to be renewed every one-and-a-half years for at least the next decade.
“Every time this crops up, it will be a great strain for all those that this happened to,” Lisbeth Royneland, whose daughter Synne would have celebrated her 29th birthday on Tuesday, told Norway’s state broadcaster NRK.
Breivik has three cells to himself in the high-security wing of Skien prison. The cells are equipped with video game consoles, a television, a DVD player, electronic typewriter, newspapers and exercise machines. He also has daily access to a larger exercise yard.
The mass murderer lost a human rights case in 2017 when an appeals court overturned the decision of a lower court that his near-isolation was inhumane. The European Court of Human Rights rejected a subsequent appeal.
