A referendum on the revision of Comoros' constitution will be held on 17 May, President Ahmed Abdallah Sambi announced in a message broadcast on national radio and television stations, stressing that the referendum campaign would be held from 26 April to 15 May. “Those who do not want the revision of the constitution are free to campaign against it but they do not have the right to prevent the referendum from being held; a constitutional prerogative devolved on the head of state is a right of the people to exercise its sovereignty,” Sambi declared.
