In Zanzibar, the country's semi-autonomous state, The Alliance for Change and Transparency-Wazalendois (ACT-Wazalendo) is considered the main opposition political party. The constitution of Zanzibar requires the party that comes in second in the polls to join a coalition with the winning party. ACT-Wazalendo joined a coalition government with the islands' ruling party Chama Cha Mapinduzi in December 2020 after Zanzibar disputed elections.
