Nigel Mansell led the race until lap 70, but then suffered a loose wheel nut and was forced into the pits, emerging behind Ayrton Senna. The pair duelled around Monaco for the final three laps but Mansell could find no way past, finishing behind the Brazilian.
Kimi Räikkönen won the race after starting from 17th position and overtaking race leader Giancarlo Fisichella on the final lap. It was his final victory for McLaren.
James Hunt crossed the finish line in first position but the Ferrari, Tyrrell and Copersucar teams protested the result to the stewards, because of a crash at first corner. In September, two months after the event, a decision was reached & Hunt was disqualified, giving Niki Lauda the race win.
Despite Senna stalled on the grid & had dropped to 14th place, he immediately made a charge through the field and managed to force his way through as leader Prost was trying to deal with a malfunctioning gearbox & a tricky wet/dry surface. With victory in the race, Senna clinched his first F1 title.
