One of French Polynesia's members of the French assembly, Bruno Sandras, has lashed out at the territory's opposition leaders, likening their threats to unseat the government to a crime.
Mr Sandras says suggestions by Gaston Flosse and Oscar Temaru that a motion of no confidence is imminent is part of a power struggle and not a fight for the common good.
His comments come as the government of Gaston Tong Sang struggles to muster a majority.
Mr Sandras says the administration has difficulty meeting its obligations and a change of government would incur further costs.
The French overseas territories minister, Marie Luce Penchard, is due in Tahiti this week to continue discussions about reforms to increase political stability.
