The Democratic Alliance (DA) is a South African political party and the official opposition to the governing African National Congress (ANC). The present leader is Mmusi Maimane, who succeeded former Mayor of Cape Town and Premier of the Western Cape Helen Zille on 10 May 2015. The party is broadly centrist, though it has been attributed both centre-left and centre-right policies. It is a member of the Liberal International and the Africa Liberal Network. The DA traces its roots to the founding of the anti-apartheid Progressive Party in 1959, with many mergers and name changes between that time and the present. The party adopted its current name on 24 June 2000. Most recently, it has integrated the smaller Independent Democrats and the tiny South African Democratic Convention.
