Jenson Button claimed pole position for the Monaco Grand Prix in a hard-fought and unpredictable final phase of qualifying, as the majority of the ten drivers remaining in the field appeared capable of taking top spot.
Sebastian Vettel and Nico Rosberg shared top spot between them for nine of the ten minutes, but Kimi Raikkonen and Button both went better than the two Germans in the final moments, with the Briton bouncing back from a disappointing second phase to claim a fourth pole for the year.
Brawn team-mate Rubens Barrichello and Vettel both had later attempts to claim top spot, but both came up short, dropping into third and fourth respectively, while Felipe Massa had to settle for fifth, sharing row three with Rosberg, whose own final attempt also came up short.
Heikki Kovalainen was unable to make up for Lewis Hamilton's early exit, taking seventh spot, while Mark Webber could only manage eighth after not leaving the pit-lane in the first half of the session. As expected, Fernando Alonso and Kazuki Nakajima rounded out the top ten.
