Mark Webber will start on pole for the second time this season after beating Red Bull team-mate Sebastian Vettel to top spot in qualifying for the Korean Grand Prix.
The Australian was quickest when it really mattered in Yeongam as he took his first pole since the Monaco Grand Prix back in May with Vettel forced to settle for second as Red Bull locked out the front row for the second successive race.
Vettel had led the way in both the first and second stage of the session and looked set to secure pole himself when he went comfortably quicker than his rivals on his first run in Q3.
Webber responded however to move to the head of the field but had most his rivals behind him on track seeking to better his time. None were able to demote him from the top of the pack however, with Vettel losing out in the first sector and failing to improve his time as he ended up just 0.074secs behind.
Lewis Hamilton was best of the rest in third place, two-tenths of a second further back, although the McLaren man had earlier suffered a scare in Q1 when he found himself tumbling down the order in the closing moments while sitting in the pits. Luckily for the Briton, Bruno Senna was forced to abort his final flying lap for Williams and was unable to knock the 2008 title winner into the drop zone – allowing him to continue in the latter stages of the session having saved a set of the quicker super-soft tyres.
Hamilton will be joined on row two by points leader Fernando Alonso, who used a set of super-soft rubber in Q1 to ensure he didn't risk falling at the first hurdle, with Kimi Raikkonen's Lotus and the second Ferrari of Felipe Massa sharing row three.
Romain Grosjean, Nico Hulkenberg, Nico Rosberg and Michael Schumacher rounded out the top ten.
Jenson Button was the big name to fall before Q3 having fallen foul of a yellow flag in the closing stages of the second phase of the session.
A gearbox issue forced Toro Rosso's Daniel Ricciardo to park his car on the side of the circuit in the final sector, with Button then losing time when he backed off on his second run – falling just shy of the top ten shoot-out in the process.
Button had earlier lost time when he made an error on his first qualifying run, although the Briton wasn't helped by the fact that others improved their times when the yellow flags were out to knock him into the drop zone.
