1983 saw Prost win his first of five British Grands Prix and a spectacular performance from Briton Nigel Mansell in his first outing in a turbocharged Lotus, he started 16th and finished 4th. Lauda won again at Brands Hatch in 1984, during which FISA president Jean-Marie Balestre announced that the Tyrrell team was to be excluded from that year's championship for fuel irregularities, and the restarted race after a huge accident at Bottom Bend caused more controversy; Prost and Lauda had passed Brazilian Nelson Piquet on the last lap of the first race, but Piquet started in front of the two McLaren drivers; regulations dictated that the positions were on the grid were to be determined two laps before the restart was called; and an irate Prost made scathing comments about his countryman Balestre.
