Which South African President repealed key parts of apartheid law?

Frederik Willem de Klerk DMS (born 18 March 1936) is a South African politician who served as State President of South Africa from 1989 to 1994 and as Deputy President from 1994 to 1996. As South Africa's last head of state from the era of white-minority rule, he and his government dismantled the apartheid system and introduced universal suffrage. Ideologically a conservative and an economic liberal, he led the National Party from 1989 to 1997.

On 2 February 1990 he gave an address to the country's parliament in which he announced plans for sweeping reforms of the political system. He announced that a number of banned political parties, including the ANC and Communist Party of South Africa, would be legalised, although stipulated that this did not constitute an endorsement of their socialist economic policies nor of violent actions carried out by their members. He also announced that the Separate Amenities Act of 1953, which governed the segregation of public facilities, would be lifted.

His speech revealed that all of those who were imprisoned solely for belonging to a banned organisation would be freed. He declared that Mandela would be released from prison unconditionally; the latter was released a week later. The vision set forth in de Klerk's address was for South Africa to become a Western-style liberal democracy; it envisioned a market-oriented economy which privileged private enterprise and restricted the government's role in economics.
