Initially it was thought that long-time president
José Eduardo dos Santos would lead the ruling
MPLA into the election before possibly stepping down in 2018, but in December 2016 the MPLA designated
João Lourenço, the minister of defense and vice-president of the MPLA, as the party's top candidate and therefore its presidential candidate. Lourenço was viewed as strongly loyal to dos Santos.
Bornito de Sousa was designated as the party's vice-presidential candidate. In April 2017, the Council of the Republic, which acts as an advisory body to the president, proposed holding the election on 23 August 2017. It was announced on 26 April that dos Santos had formally approved the proposed date. In early July 2017, National Electoral Commission (CNE) stated that it was expecting 3,000 national and international election observers in the country during the elections. On 21 July 2017, the National Assembly approved legislation that would keep top security officials (the chiefs of the army, police and intelligence) in place for eight years, thereby preventing presidents from choosing the occupants of those posts at will. The official campaign period ran from 22 July to 21 August. == Electoral system ==
