Australian Mark Webber steered his Red Bull to victory and claimed his first win this year and his team's third successive Monaco Grand Prix victory on Sunday.
It also meant six different drivers have won the opening six races of this season - the first time this has happened in the history of the Formula One world championship.
Starting from pole, Webber finished the 78-laps race six-tenths of a second clear of second-placed German Nico Rosberg of Mercedes with Spaniard Fernando Alonso third for Ferrari.
Sebastian Vettel was fourth for Red Bull ahead of Lewis Hamilton in his Mclaren.
