Breivik murdered 77 people in central Oslo and the Norwegian island of Utöya in the name of right wing extremism in July of 2011.
Since the trial was opened on April 16, legal psychiatrists have been divided on the question of Breivik's mental health. The judgement of whether Breivik was accountable for his actions, or whether they were the doings of a mad man, was an important factor in deciding his sentence.
The trial saw two conflicting assessments of Breivik's mental health, one attesting to his sanity and the other claiming he suffered from a psychotic attack when he carried out the terror acts.
Breivik himself has maintained throughout the case that he was accountable for his actions, and has said that he wants to accept his sentence.
According to a survey conducted by research agency Sifo, three out of five Swedes think Breivik should be given a prison sentence rather than be sentenced to care in a psychiatric ward, reports news agency TT. The reactions to the prison sentence is Sweden have been positive.
Former head of the Swedish Social Democrat youth organisation SSU Jytte Guteland told Swedish Television that for many people who survived the attacks on Utöya, the verdict comes as a relief.
"Many people who were on the island have wanted to see this - him taking responsibility for his actions", she said.
Radio Sweden will be covering Swedish reactions to the verdict in Friday's programme.
