The man who has confessed to the twin terror attacks in Norway which killed 93 people will appear in court today and has requested an open hearing so he can explain his massacre to the public.

Oslo District Court spokeswoman Irene Ramm has said government lawyers will request eight weeks of pre-trial detention for the Norway attacks suspect so they can prepare their case.

The stepbrother of Crown Princess Mette-Marit was among the 86 people killed when a gunman opened fire at a youth camp in Norway, the royal court said today.
