A new constitution for this war-ravaged Central African nation was approved by a landslide vote, paving the way for historic presidential and parliamentary elections in March, according to electoral results released late Wednesday. The balloting in December approved a charter that grants greater autonomy to mineral-rich provinces and lowers the minimum age for presidential candidates from 35 to 30 - allowing an election bid by 34-year-old President Joseph Kabila, who has ruled since his father's 2001 assassination. Electoral commission chief Appolinaire Malumalu said 84 percent had voted in favor of the constitution, compared to 16 percent against.
