the President, the Vice-Presidents and the Council of Ministers. The legislative branch comprises a 220-seat unicameral legislature, the National Assembly of Angola, elected from multi-member province-wide and nationwide constituencies using party-list proportional representation. For decades, political power has been concentrated in the presidency. After 38 years of rule, in 2017 President dos Santos stepped down from MPLA leadership. The leader of the winning party at the parliamentary elections in August 2017 would become the next president of Angola. The MPLA selected the former Defense Minister João Lourenço as Santos' chosen successor. Out of 32 ministers there were 12 women. In what has been described as a political purge to cement his power and reduce the influence of the Dos Santos family, Lourenço subsequently sacked the chief of the national police, Ambrósio de Lemos, and the head of the intelligence service, Apolinário José Pereira. Both are considered allies of former president Dos Santos. He also removed Isabel Dos Santos, daughter of the former president, as head of the country's state oil company Sonangol. In August 2020, José Filomeno dos Santos, son of Angola's former president, was sentenced for five years in jail for fraud and corruption. Constitution The Constitution of 2010 establishes the broad outlines of government structure and delineates the rights and duties of citizens. The legal system is based on Portuguese law and customary law but is weak and fragmented, and courts operate in only 12 of more than 140 municipalities. A Supreme Court serves as the appellate tribunal; a Constitutional Court does not hold the powers of judicial review. Governors of the 18 provinces are appointed by the president. After the end of the civil war, the regime came under pressure from within as well as from the international community to become more democratic and less authoritarian. Its reaction was to implement a number of changes without substantially changing its character. The new constitution, adopted in 2010, did away with presidential elections, introducing a system in which the president and the vice-president of the political party that wins the parliamentary elections automatically become president and vice-president. Directly or indirectly, the president controls all other organs of the state, so there is de facto no separation of powers. In the classifications used in constitutional law, this government falls under the category of authoritarian regime. Armed forces The Angolan Armed Forces (Forças Armadas Angolanas, FAA) are headed by a Chief
