Pastor Maldonado has become the first Venezuelan to win a Grand Prix after he emerged victorious in the Spanish Grand Prix.
Maldonado started from pole but lost out to Fernando Alonso at the start.
From there, Williams decided to pit Maldonado earlier for his third stop and despite a slow wheel change, he leapt ahead of Alonso.
Lotus's Kimi Raikkonen completed the podium.
Sebastian Vettel could only finish 6th, but crucially ahead of Lewis Hamilton (8th) and Jenson Button (9th). Mark Webber failed to score.
The result means Williams pick up their first victory since Brazil 2004.
A full race review will follow.
