Max Verstappen has threatened to walk away from Formula 1 if the sport's top bosses continue to experiment with the race weekend format.
The introduction of the Sprint has been the significant change in recent times, with the alternative weekend structure used at three races in each of the last two seasons. This year, the programme has been extended to six Grands Prix of the 23.
Verstappen has already made it clear he is not a fan of the short-form races and prefers the usual weekend format of qualifying on a Saturday and then the race the following day. Not only is the Sprint programme expanding, but further changes are being mooted.
