Lewis Hamilton called upon the FIA to step in to curb Red Bull's dominance, accusing the governing body of allowing teams to dominate Formula 1 for years.
Red Bull are the defending constructors' champions, having ended an eight-year Mercedes streak last season. And Max Verstappen has won the last two drivers' titles.
And both look set to add more silverware this season. Red Bull have been well ahead of everyone else in terms of car performance, while Verstappen has barely put a foot wrong to win six of eight races so far – team-mate Sergio Perez taking victories in the other two.
