French Polynesia's Tahoeraa Huiraatira Party has lost another assembly member who is siding with the ruling majority.
Media reports in Tahiti say Jacques Raioha quit the Tahoeraa whose numbers have dwindled from 38 to 17 since the party began splintering in 2014.
His defection gives the government side led by Edouard Fritch 30 seats in the 57-strong assembly.
The Tahoeraa decline began shortly after its leader Gaston Flosse lost office over a corruption conviction.
The split was formalised when his erstwhile deputy and now president, Edouard Fritch, formed his own party last month.
