Ivory Coast President Alassane Ouattara's governing coalition splits over feud
"The political bureau has decided to withdraw," from the coalition, said PDCI spokesman Narcisse N'Dri.
A recent rift, exacerbated in part by an Ouattara cabinet reshuffle in July, strained relations and put the coalition at risk ahead of local elections next month and a presidential election in 2020.
It also threatens to aggravate instability in Ivory Coast, where a tenuous stability has held since a brief civil war in 2010-11 that killed 3,000 people. Since then the economy has grown rapidly.
Now, Bedie is looking for other allies, which could weaken Ouattara's RDR party further.
"The Political Bureau mandates President Bedie, to start negotiations for the establishment of a platform for collaboration with Ivorians who share his vision of a reconciled and peaceful Ivory Coast," N'Dri said.
