A former French minister in charge of overseas territories, Christian Paul, has warned of trouble in French Polynesia if no new elections are held.
His comments come after the French government declined a request to let French Polynesia go to the polls.
The requested has been made both before and after the demise of the new government.
The ruling coalition led by Oscar Temaru lost power because one of its members, Noa Tetuanui, sided with the opposition in a no confidence vote.
Mr Paul, who is now an MP for the opposition Socialist Party, says only a full vote by the people can now avert trouble, revenge and provocations.
He says from the beginning of its tenure, the Temaru administration was put into doubt by the French government.
The French government has dismissed accusations that it had a hand in the ousting of the Temaru government.
