Ivory Coast ex-president Laurent Gbagbo on Monday proposed setting up a new political party, his deeply-divided Ivorian Popular Front (FPI) announced.
At a crunch meeting of party leaders, Gbagbo lashed out at his former prime minister, Pascal Affi N'Guessan, the FPI's president, and proposed "creating a new instrument of struggle in line with our ideology and ambitions", the FPI said.
A congress to set it up could take place in October, it said.
Gbagbo, 76, was in power for a turbulent decade from 2000-11.
In 2010, he refused to concede election defeat to the current president, Alassane Ouattara, sparking a months-long civil conflict that claimed some 3,000 lives.
He returned to national politics in June after being dramatically acquitted at the International Criminal Court of crimes against humanity arising from the bloodshed.
During his years in prison in The Hague, a deep rift developed in the FPI, which Gbagbo founded in 1982.
One side is headed by 68-year-old Affi N'Guessan, who leads a so-called "legal" faction -- a term that stems from the judicial authorities' acknowledgement of his position as party president in 2015.
The other side is the so-called "GOR" faction -- from the French words meaning "Gbagbo Or Nothing" -- backed by grassroots members who fervently support the former president.
- 'Confiscated' -
Monday's statement quoted Gbagbo as saying that the FPI, "our sole instrument of political struggle, has been confiscated by Mr. Affi N'Guessan, and despite the many attempts to reason with him, he insists on his so-called 'legality'."
Gbagbo "has acknowledged Mr. Affi N'Guessan's willingness and stubbornness to take the FPI hostage, trampling on years of sacrifice by the men and women who are party militants".
He asked the FPI's central committee to authorise setting up a committee to prepare for a "constitutive congress" to create a new party, the statement said.
Several attempts to bridge the rift following Gbagbo's return failed, and last week the "legal" faction mounted a rearguard action after the former president convened a meeting of the party leadership.
The faction said that Gbagbo, despite his status as a "founder member of the party," was not the "current president" of it.
The "legal" FPI "will fight the cult of personality, autocracy, the road to dictatorship, with all its strength", it added.
Gbagbo, a powerful orator, rose in the 1970s as a left-wing campaigner who helped end Ivory Coast's one-party system following independence from France in 1960.
He wields significant clout among poorer Ivorians, who see him as a supporter of the underdog.
