"[15] On February 26, 2015, two days before the PDCI congress that would officially back Ouattara as the only RHDP candidate, KKB and three other party members (former Prime Minister Charles Konan Banny, former Foreign Minister Amara Essy, and parliament member Jérôme Kablan Brou) announced their decision not to attend the event.

In the election on October 25, he came in third place with 3.88% of the vote, behind the incumbent Outtara at 83.66% and the Ivorian Popular Front candidate Pascal Affi N’Guessan at 9.29%.

"[23] Dissent subsequently increased between the two main allied parties of the RHDP, with Bédié declaring that the alliance as it was in 2005 "no longer existed."

[33] Against the backdrop of pre-electoral violence and one month before the vote on October 31, Bédié called for "civil disobedience.

"[37] In an interview with Jeune Afrique on October 1, KKB reiterated his refusal to support the two candidates' call for a boycott of the election.

"[39][40][41] Despite his insistence on staying in the race, he "commands little broad support" and was not expected to defeat the incumbent Ouattara.
