Voters elect delegates to Municipal Assemblies in competitive elections. There is only one political party, the Communist Party, but since there must be a minimum of two candidates, members of the Communist Party often run against each other. Candidates are not required to be members of the party. They are nominated directly by citizens in open meetings within each election district. Municipal Assembly delegates in turn elect members of the Provincial Assembly, which in Havana serves roughly as the City Council; its president functions as the Mayor. There are direct elections for deputies to the National Assembly based on slates, and a portion of the candidates is nominated at the local level. The People's Councils (Consejos Populares) consist of local municipal delegates who elect a full-time representative to preside over the body. In addition, there is involvement of "mass organizations" and representatives of local government agencies, industries and services. The 105 People's Councils in Havana cover an average of 20,000 residents.
