For the decade from 1984 to 1993 the race was won by only two drivers, arguably the two best drivers in Formula One at the time – Frenchman Alain Prost and Brazilian Ayrton Senna. Prost, already a winner of the support race for Formula Three cars in 1979, took his first Monaco win at the 1984 race. The race started 45 minutes late after heavy rain. Prost led briefly before Nigel Mansell overtook him on lap 11. Mansell crashed out five laps later, letting Prost back into the lead. On lap 27, Prost led from Ayrton Senna's Toleman and Stefan Bellof's Tyrrell. Senna was catching Prost and Bellof was catching both of them in the only naturally aspirated car in the race. However, on lap 31, the race was controversially stopped with conditions deemed to be undriveable. Later, FISA fined the clerk of the course, Jacky Ickx, $6,000 and suspended his licence for not consulting the stewards before stopping the race. The drivers received only half of the points that would usually be awarded, as the race had been stopped before two-thirds of the intended race distance had been completed.
