Congolese main opposition figures, leader of the Union for Democracy and Social Progress (UDPS), Felix Tshisekedi (R) and his running mate leader of the Union for the Congolese Nation (Union pour la Nation Congolaise, UNC) Vital Kamerhe(L) wave from a car to their supporters after arriving on November 27, 2018 in Kinshasa. - Tens of thousands of supporters turned out to welcome Congolese opposition scion Felix Tshisekedi as he returned to Kinshasa on November 27, 2018 to kick off his campaign to replace President Joseph Kabila in next month's election. Their decision to run on a joint ticket came just days after the pair had withdrawn their support for an agreement hammered out in Geneva in which seven opposition parties coalesced around a joint candidate in order to boost the opposition's chance of victory.
