(CNN) -- Australian Mark Webber has taken over at the top of Formula One drivers' standings after a line-to-flag victory in the Monaco Grand Prix -- the sixth race in the calendar.
Webber followed up his all-the-way success in Spain the previous week by repeating that feat, with Red Bull teammate Sebastian Vettel chasing him home in second place.
The result means the pair are locked together at the top of the standings on 78 points, but Webber leads the way by virtue of having won two races to the German's one this season.
Two-time world champion Fernando Alonso is only three points behind in third place after finishing seventh in Monaco -- despite starting from the pit lane.
However, world champion Jenson Button -- who led the way going into the Monaco race -- has slipped to fourth after a mechanical failure meant he picked up no points on Sunday.
In the constructors' standings, Red Bull have now opened up a 20-point lead over Ferrari with McLaren a further seven adrift in a fascinating three-team race for honors.
