Saudi Arabia's powerful interior minister Prince Nayef bin Abdul Aziz late Thursday was named crown prince after the death of his brother Sultan. According to AFP, 78 year old Nayef is seen as more conservative than his half brother King Abdullah, 87. Nayef also suffers from health problems.
According to experts on the Saudi monarchy, Nayef was treated abroad in April for cancer. The new crown prince is also known for his close relations with the kingdom's religious establishment and is believed to oppose reforms that could liberalize the Saudi society.
