The defence team, led by Geir Lippestad, have confirmed that they are left with no choice but to follow their client's wishes and request an acquittal.
"He is going to invoke self-defence. We of course understand that it won't take us forward, but it is our duty to present his arguments," Lippestad told the Dagbladet daily.
"What we will do is pose questions that give him the opportunity to explain what he means," he added.
Geir Lippestad underlined that it is the job of the defence counsel to follow the requirements of a client, "especially when we can see that it doesn't put him in any worse position than he is already in".
During at least one of the meetings with Breivik in detention, the 33-year-old has demanded his immediate release.
Breivik has said that the terror attacks committed in Oslo and on Utøya island on July 22nd were conducted in a defence of Norwegian culture from what he believes to be devastating multiculturalism.
The trial against Anders Behring Breivik begins at Oslo District Court on Monday.
