Mark Webber has taken his second grand prix victory on the trot, this time having to soak up immense pressure to win the Monaco Grand Prix as several race-winning margins were eroded by safety car periods.
The Australian led home team-mate Sebastian Vettel in a Red Bull one-two that put the duo equal at the head of the driver's championship standings - although Webber holds top spot on account of his superior number of podiums.
Front row starter Robert Kubica (Renault) had to settle for third after losing out to Vettel off the line at the start of the race.
Pre-race championship leader Jenson Button was an early retirement, his car overheating after McLaren left a radiator bung in for the formation lap, but Fernando Alonso (Ferrari) kept himself in title contention by coming through from last to seventh after a canny strategy.
As well as charging through the field, Alonso was at the centre of another talking point when he was overtaken by Michael Schumacher (Mercedes) on the final corner of the race.
With the safety car peeling in on the last turn to let the event finish under race conditions, drivers were expected to follow each other across the line. However, Alonso ran a little wide and the following Schumacher ducked up the inside to snatch a cheeky sixth.
