The Francophonie summit due to be held in Tunisia in November has been postponed, the international organisation has said.
The 88 French-speaking countries were scheduled to meet in the island of Djerba next month but have decided to move the event to next year.
The decision is believed to be partly motivated by the political situation in Tunisia.
The North African country has been under "exceptional measures" since July when President Kais Saied suspended parliament and fired the prime minister in a move deemed a violation of the constitution by his critics, however many Tunisians have supported Mr Saied.
The delay of the Francophonie summit is seen by the opposition as a blow to the president and his power grab.
