South Africa's President Cyril Ramaphosa has unveiled a new coalition government after his ruling African National Congress party lost its parliamentary majority in May's elections. He says the government of national unity is unprecedented in the history of democracy. The ANC will have 20 out of 32 cabinet posts, while the Democratic Alliance (DA) - until now the main opposition party - will hold six. Six other portfolios are shared amongst smaller parties. In the new cabinet, the ANC will keep key ministries such as defence, finance and foreign affairs. The DA's portfolios include home affairs and public works. Party leader John Steenhuisen will lead the agriculture ministry.
