OSLO, Norway - The head of the panel that will review the Norway gunman's psychiatric evaluation has told The Associated Press that it's unlikely the suspect will be declared legally insane.

Dr. Tarjei Rygnestad, who heads the Norwegian Board of Forensic Medicine, tells the AP that Anders Behring Breivik appears to have been in control of his actions.

Norway, an insanity defence requires that a defendant was in a state of psychosis during the crime, meaning he lost contact with reality to the point that he's no longer in control.

"It's not very likely he was psychotic," Rygnestad told AP.

The board must review and approve an evaluation conducted by two court-appointed psychiatrists before a judge decides whether Breivik can be held criminally liable.
