Sunday 7th September 1986

Nelson Piquet led home team-mate Nigel Mansell for a Williams 1-2 with Stefan Johansson grabbing third for Ferrari at the Italian Grand Prix. Teo Fabi and Alain Prost had qualified on the front row but problems with their respective cars meant Fabi started from the back and Prost from the pitlane. After overtaking Mansell, Piquet marched on to a dominant win to move himself back to second in the standings, five points behind Mansell.
