7 February 1986
Dr Frederik van Zyl Slabbert, a staunch opponent of 'separate development' (Apartheid) and leader of the opposition Progressive Federal Party (PFP), resigned as leader of the PFP and as a MP. In his dramatic announcement he stated that he came to the conclusion that Parliament was incapable of bringing about the desired reforms. Slabbert came from an Afrikaner family and studied sociology at the University of Stellenbosch. He published a book, The Last White Parliament, after his resignation. In the book he explains his reasons for resigning and his predictions for South Africa. In 2002, then President Thabo Mbeki appointed him to head a team investigating a new electoral system for South Africa. Slabbert passed away on 14 May 2010.
