During his statement, Breivik showed no remorse and made no admission of guilt. ITN's Paul Davies reports.
Self-confessed mass killer Anders Behring Breivik told his trial in Norway Tuesday that he was motivated by "goodness, not evil" and said, "I would have done it again."
On the second day of his trial, he boasted about last July's massacre in a pre-pepared statement to court, saying: "I have carried out the most sophisticated and spectacular political attack committed in Europe since the Second World War."
Breivik, 33, has said he acted to protect his country by setting off a car bomb that killed eight people at government headquarters in Oslo last July, then killing another 69 people in a shooting spree at a youth summer camp organized by the ruling Labor Party.
He has pleaded not guilty, saying he acted in defense of Norway against multiculturalism.
The trial will turn on whether Breivik is found guilty or insane.

Norwegian mass killer Anders Behring Breivik at the start of the second day of his terrorism and murder trial in Oslo, Tuesday.
While he risks being kept behind bars for the rest of his life, the high school dropout has said being labeled insane would be a "fate worse than death."
Breivik spoke for longer than the 30 minutes allotted for his 13-page statement, and was asked to finish by the judge. The statement is the start of an expected five days of testimony from Breivik before other witnesses are called.
Breivik insisted he should continue, telling the judge, "I never asked for 5 days, I just want 1 hour to explain myself," Sky News journalist Trygve Sorvaag reported on Twitter.
Breivik said the aim of the massacre was to end "multicultural drift", and set out his views on Muslims and sharia law. A court order prohibited broadcasters from showing pictures from inside the court while Breivik was speaking.
"People will understand me one day and see that multiculturism has failed," he said. "If I am right, how can what I did be illegal?"
"They (Norwegians) risk being a minority in their own capital in their own country in the future," he added.
Reporters inside the court described Breivik as "rambling", and said the court - in particular, relatives of the victims - grew impatient with the speech.
BBC reporter Matthew Price posted a picture of Breivik in the courtroom on Twitter after his speech had finished.
Earlier Tuesday, one of the lay judges hearing the case was dismissed after it emerged he had posted a comment on a Facebook page saying Breivik should face the death penalty.
Shortly after the killings, Thomas Indrebø posted "the death penalty is the only just outcome of this case."
Breivik's defense lawyer said Indrebø should be dismissed from the case because of the remark, and it was later announced he would be replaced by a reserve lay judge.
The trial began on Monday, with two professional judges, as well as three lay judges chosen from civil society, presiding over the court.
The lay judge's dismissal is not expected to lead to any mistrial verdict.
Confessed killer Anders Breivik returned to the Norwegian youth camp where he killed 69 people to reenact his bloodbath for police. NBC's Michelle Kosinski reports.
Norway's VG newspaper reported the text of Indrebø's posting, according to a translation posted on The Telegraph news website.
"The death penalty is the only just sentence in this case!!!!!!!!!!" read the message. The Telegraph said the comment was posted below an article in VG only a day after Breivik killed 77 people with a bomb and gunfire.
A previous version of the story quoted Breivik as saying he "would do it all again," rather than "I would have done it again," based on a translation by Sky News.
