McLaren pit-stop error scuppers Hamilton's chances
Rubens Barrichello took advantage of a poor McLaren pit-stop to win the European Grand Prix in Valencia.
Lewis Hamilton looked set for a second consecutive victory but he was delayed in the pits and eventually had to settle for second place.
World championship leader Jenson Button had a miserable afternoon and could only manage seventh but his two nearest challengers, Mark Webber and Sebastian Vettel, fared even worse.
Kimi Raikkonen made steady progress throughout the race, eventually claiming his third podium of the season behind Barrichello and Hamilton.
Veteran Barrichello has taken nine previous race victories, but his win at the Spanish track is his first for new team Brawn GP.
Heikki Kovalainen took fourth place with Nico Rosberg hot on his tail, with home favourite Fernando Alonso, Button and Robert Kubica collecting the rest of the points on offer.
Start
The two McLarens had made a clean getaway from the front-row but Button had a terrible first lap, slipping from fifth to eighth.
As Hamilton and Kovalainen pulled away at the head of the field, the third-placed Brawn of Barrichello came under attack from Raikkonen.
Reigning world champion Hamilton immediately began to race away from his team-mate, setting consecutive fastest laps in the early stages.
Button was forced to concede another place as he had cut a chicane in order to stay ahead of Webber and so let the Red Bull through in order to avoid a penalty.
Barrichello was looking to take advantage of a slightly heavier fuel load than the two cars in front of him, but was unable to keep a flying Hamilton in his sights early on.
After letting his championship rival through, Button could not mount a challenge for Webber's eighth place and remained mired in the midfield as the first pit-stops approached.
Hamilton was the first of the front-runners to stop on lap 16, followed next time around by team-mate Kovalainen while Barrichello stayed out and upped the pace.
Lead Change
The Brazilian managed to leap-frog into second place with a string of great in-laps, rejoining just a couple of seconds behind the race leader.
Button almost managed to climb into the points when Vettel encountered refuelling problems during his first pit-stop and had to come in again, but the heavily-fuelled Giancarlo Fisichella temporarily halted his progress.
The German then suffered a mechanical failure, suspected to be an engine problem, on lap 25 and coasted to a halt out on the circuit.
Barrichello pegged the McLaren back during the second stint, attempting to keep the gap down to a handful of seconds in order to make his move during the final pit-stop window.
But when Hamilton entered the pit-lane for his second stop his tyre men were not in position and the 24-year-old lost crucial seconds as he waited.
The delay was all Barrichello needed and he emerged from his second pit-stop comfortably in the lead.
Webber's pace dropped off significantly in the later stages and Button was able to capitalise, getting ahead of the Australian to score what could prove to be two vital points in the race for the title.
Almost unnoticed, Raikkonen leap-frogged compatriot Kovalainen at the second round of stops thanks to a string of flying laps before he pitted.
Once he was behind the 37-year-old, Hamilton could not make any inroads and eventually trailed Barrichello
