Anders Behring Breivik's defense lawyers say the confessed mass killer won't appeal if he's sentenced to prison but he will challenge any ruling that declares him insane.

Breivik's mental state will be the focus when the Oslo district court presents its judgment against Breivik on Friday for the bomb and gun attacks that killed 77 people in July last year.

After speaking to Breivik on Thursday, defense lawyer Geir Lippestad said his client would accept a prison sentence and would only appeal if committed to psychiatric care.

Breivik, who claims he is a "militant nationalist," said during the trial that being sent to an insane asylum would be the worst thing that could happen to him and accused Norwegian authorities of trying to cast him as sick to deflate his political views.
