Silverstone, England - Valtteri Bottas beat crowd favourite and Formula One leader Lewis Hamilton by a wafer-thin margin on Saturday to deny his Mercedes team-mate a fifth successive British Grand Prix pole position.
The Finn was a mere 0.006 of a second quicker than the five times world champion as the two Silver Arrows once again locked out the front row of the grid on a cloudy afternoon at Silverstone.
Ferrari's young Monegasque Charles Leclerc will share the second row with Red Bull's Max Verstappen, who won the previous race in Austria where the two 21-year-olds clashed on track while fighting for victory in the closing laps.
The pole, in a time of one minute 25.093 seconds, was Bottas's fourth in 10 races this season - more than any other driver - and career 10th.
"Ultimately not good enough," said Hamilton, who was fastest in the first phase of qualifying, of his performance. "We worked really hard throughout the session but it just got a little bit away from us.
