Nelson Mandela's African National Congress formed a government of national unity with F. W. de Klerk's National Party and Mangosuthu Buthelezi's Inkatha Freedom Party. The three racially based houses from previous parliaments were replaced with the re-introduced Senate and National Assembly. In 1997, on the introduction of the final Constitution, the Senate was replaced by the National Council of Provinces, which continues to serve as the upper house of South Africa's Parliament.
