The incumbent Joseph Kabila has won the presidential election in the Democratic Republic of Congo, the Independent Electoral Commission said on Thursday, announcing provisional results.
Kabila, 35, took 58.05 per cent of the vote in the October 29 run-off, compared with 41.9 per cent for his rival vice-president Jean-Pierre Bemba, the commission said.
Turnout was 65.3 per cent of some 25.4 million eligible voters.
Under electoral rules, the candidates have three days to lodge suits at the Supreme Court, which is expected to formally declare the winner at the end of this month.
Tensions ran high in the capital Kinshasa after Bemba's side complained of "systematic errors" in the compiling of figures from around a country almost the size of western Europe, but with few roads and ruined infrastructure.
After first-round results were released in August, heavy fighting broke out in Kinshasa between Kabila's guard and troops on Bemba's side, claiming at least 23 lives.
Four people were killed in renewed clashes near Bemba's official residence on Saturday.
Kabila, who came to power after the assassination of his father Laurent-Desire Kabila in 2001, pledged earlier today to install a coalition government if he won the election.
