The son of Etienne Tshisekedi, the Democratic Republic of Congo’s late opposition leader, has been chosen as his father’s successor.
Felix Tshisekedi, 53, will now lead the opposition coalition in crucial negotiations over the departure of President Joseph Kabila from office.
Under a deal agreed last year, new elections would be held by the end of 2017 and Mr Kabila would not run.
It followed deadly protests calling for the president to step down.
Mr Kabila’s final mandate ran out in November 2016.
DR Congo has never had a smooth transfer of power since independence more than 55 years ago.
Mr Kabila took power in 2001 following the assassination of his father, Laurent Kabila.
He has won two elections and the constitution bars him from running for a third term.
