Spanish Grand Prix:Jenson Button will be in pole position for tomorrow's Spanish Grand Prix as he goes in search of his fourth win in five races for Brawn GP. The championship leader snatched the advantage away from Red Bull's Sebastian Vettel with a last-gasp flying lap.
Rubens Barrichello qualified third for Brawn, with Ferrari's Felipe Massa alongside on an all-Brazilian second row.
"I wished to have the pole but at the last minute he took it away," said the disappointed German, the only driver other than Brawn GP's Briton to have won this season.
Button now has a good chance to take his fourth victory in five races, knowing the driver on pole has won in Barcelona for the past eight years and 13 times in the past 14 at the Circuit de Catalunya.
He left it late before heading out for his final flying lap, the 29-year-old leaving himself no room for error in making it round the track before the session ended.
"It could have gone very, very wrong," he said. "I think I just got across the line with a couple of seconds to spare."
Button won from pole in Australia and Malaysia but had not qualified in the top three for the past two races. Saturday's was the sixth pole of his career.
Australian Mark Webber was fifth quickest for Red Bull, Brawn's closest rivals, just ahead of the Toyotas of Timo Glock and Jarno Trulli.
Spain's double world champion Fernando Alonso will start eighth for Renault.
While Massa, who will get a boost at the start from the KERS energy recovery system that the cars ahead of him do not have, could be pleased with his afternoon's work there were still red faces at Ferrari.
Finland's Kimi Raikkonen, the 2007 world champion who won in Barcelona last year, qualified only 16th.
McLaren also had a nightmare day with Britain's world champion Lewis Hamilton 14th and team mate Heikki Kovalainen 18th.
