Mark Webber turned anger into an astonishing British Grand Prix win as Red Bull team-mate Sebastian Vettel again failed to convert pole into victory.
Vettel sustained a puncture after making the faintest of contact with Lewis Hamilton on the first corner during an enthralling start in front of a 120,000-strong crowd at a sunny Silverstone.
Webber eventually claimed his third win of the year by 1.3 seconds from McLaren's Hamilton, who has extended his championship lead to 12 points. Mercedes' Nico Rosberg claimed third, depriving Jenson Button of his first podium on home soil as the Briton climbed 10 places from 14th on the grid to claim fourth.
After the chequered flag came down, team principal Christian Horner told Webber over the in-car radio, said: "Well done Mark, you can smile now."
That prompted a remarkable response from Webber who said: "Well done guys - not bad for a No.2 driver!"
His comments were a response to the furore that surrounded Red Bull Racing on Saturday, with all eyes on Webber and Vettel.
Webber was clearly furious after the team removed a new front wing and handed it to Vettel ahead of qualifying after the component broke on his car in final practice.
So there was a sense of anticipation as to what would happen when the five red lights disappeared to signal the start of the 52-lap race.
From his fifth pole position this season, Vettel immediately moved to his right to squeeze Webber who was forced to take evasive action with Hamilton on the tail of the feuding pair.
The Briton was so close to Vettel the left end plate on his front wing brushed the right rear tyre of the 23-year-old's Red Bull, just enough to cause a puncture, which forced him off the track and left him making up ground for the remainder of the race, eventually salvaging seventh.
