Piquet's Italian teammate Riccardo Patrese won the race. 1984 saw the event take place early in the season, and Prost (now driving for McLaren) started from the pit lane in the spare car after his race car didn't start. This was made legal when the first start was aborted after Briton Nigel Mansell stalled on the grid. Prost drove through the field to finish 2nd behind his teammate Niki Lauda. Briton Derek Warwick completed the podium in a Renault and Brazilian future world champion Ayrton Senna scored his first point in a Toleman, finishing 6th. The 1985 race was mired in international controversy as nations began boycotting South African sporting events because of a state of emergency declared by the South African government in July of that year because of a surge of violence related to racial segregation in the country, called apartheid. Most people involved in Formula One were strongly against going to race in South Africa. Some governments tried to ban their drivers from going, and the Ligier and Renault teams did boycott the race in line with the French Government's ban on sporting events in South Africa; however French drivers Alain Prost, who had wrapped up the 1985 championship in the previous race, and Philippe Streiff, both driving for British teams, did take part. British driver Nigel Mansell won his second consecutive Formula One race and his teammate Keke Rosberg stormed around the track after 2 pitstops to take 2nd, completing a 1–2 for the Williams team. 1985 was the final South African Grand Prix until the end of apartheid, with FIA president Jean-Marie Balestre announcing days after the race that a Grand Prix would not return to the nation because of apartheid. Brief return (1992–1993) After the end of apartheid in 1991, Formula One returned to Kyalami for two Grands Prix in 1992 and 1993. The 1992 event was dominated by Mansell and the 1993 running saw an intense battle between Prost, Ayrton Senna and Michael Schumacher, with Prost taking victory. In July 1993 Kyalami was sold to the South African Automobile Association, which managed to run the facility at a profit; however, running a Formula One event proved too costly and the Grand Prix did not return, that year's race having also been the last time that F1 came to the African continent. The only South African driver to win the South African Grand Prix
