Official results show Tshisekedi, 55, beat the protégé of outgoing President Joseph Kabila, Emmanuel Ramazani Shadary, and another opposition leader, Martin Fayulu, to become leader of the world’s biggest cobalt producer.
Fayulu described the outcome as “an unacceptable electoral fraud”. The Constitutional Court has the final word on the validity of the vote.
The public legitimacy of the election may ride on the verdict of the influential body representing Congo’s Roman Catholic bishops that said that results gathered at polling stations during the December 30 vote by its 40000 observers showed a clear winner, without naming the person.
The New York Times cited a senior adviser to Kabila as saying that the Catholic monitoring group believed Fayulu, rather than Tshisekedi, won comfortably.
