Mercedes boss Toto Wolff reportedly became embroiled in a furious row with Red Bull's Christian Horner during a heated meeting of F1 team principals ahead of the Canadian Grand Prix.
Wolff has seen the Silver Arrows fall far back from their time as the most fearsome force in the sport, with new regulations seeing them drop down the grid. Instead, it is Red Bull and Ferrari who are battling for wins, with Mercedes' best finish being third so far.
Drivers George Russell and Lewis Hamilton have been beset by problems with their car bouncing when going down high-speed straights. It is an issue that has affected most teams on the grid, with some drivers calling for the FIA to step in amid safety concerns.
