Anders Behring Breivik, the 32-year-old right-wing fanatic who confessed to the deadly twin attack in Norway, has asked for a Japanese psychiatrist to perform his psychological evaluation, said defence lawyer Geir Lippestad.

"My client has expressed a wish for a Japanese expert. This wish has to do with the concept of honour. He believes that a Japanese person will understand him better than someone from Europe," Dagens Naeringsliv quoted Lippestad as saying.

So far, Breivik's mental state has been evaluated by two Norwegian psychiatrists. The two psychiatrists will make their recommendation by November 1, on the basis of which the decision will be made whether the confessed killer is mentally sound enough to stand the trial.

Several psychiatrists have already said, based the initial information available about Breivik's reasoning and personality, that he was fit enough to be tried, instead of being kept in a mental institution.

Breivik has confessed that he killed at least 76 people on July 22 in bombing in central Oslo and shooting spree at summer camp for the ruling Labor Party's youth wing on the island.

If found guilty of terrorism, Breivik could be sent behind bars for up to 21 years. The sentence could even be stretched if he is also found guilty of crimes against humanity, as per existing laws.

Breivik said it was "necessary" to take such actions to stop the "colonization" of the country by Muslims. He said the labor party must take responsibility for "driving its ideological line and keeps deconstructing Norwegian culture and mass importing Muslims".
