There is a deepening rift within French Polynesia's Tahoeraa Huiraatira Party which is to hold a weekend meeting to discuss its direction.
Its leader, Gaston Flosse, has called for the Tahoeraa ministers to quit the coalition government led by Gaston Tong Sang, saying the association has ended.
However, the ministers have so far refused to bow out of office.
Among them is his son-in-law and vice president, Edouard Fritch, who last week announced that Mr Flosse was to quit local politics at the next election.
The collapse of the coalition has deprived the government of its majority in the assembly.
The political changes of recent weeks have prompted Mr Fritch to call for the formation of a new pro-autonomy party.
