South Africa has a parliamentary system of government.
On Wednesday May 8, South Africans will elect a new National Assembly, and representatives for each of the 9 provincial legislatures.
The National Assembly consists of 400 members, elected by closed-list proportional representation.
Of these members, 200 are elected from national party lists.
The other 200 are elected from provincial party lists in each of the nine provinces.
The President of South Africa is elected by the National Assembly after the general election (held every 5 years).
What to watch for after Wednesday:
There is little doubt that the African National Congress will remain in power.
They got 62% of the vote in 2014, with their main opposition, the Democratic Alliance, a distant 22%.
For President Cyril Ramaphosa to continue his efforts to root out corruption in his own party, and get the South African economy going again, pundits say the ANC needs to get at least 55% of the vote, though (49% to 60% is projected).
The Democratic Alliance is hoping to hold on to its share of representatives (15% to 23% is projected), but that may be a challenge. They have the populist Freedom Front Plus party on their right that will draw away votes, and in the Western Cape province an ugly spat with the Mayor of Cape Town, Patricia de Lille, had her break away from the DA in 2018 to form her own party, the Good Party.
