Red Bull boss Christian Horner has called on Formula One to lay out its blueprint for the future of the sport after seeing it come under fire from race promoters on the eve of the 2019 season.
Last week, the Formula One Promoters' Association (FOPA), which represents 16 of the sport's existing venues, flagged concerns about pay TV deals, a lack of clarity over new initiatives and the introduction of new venues at the expense of races with a long tradition on the calendar. In a wide-ranging interview with ESPN on Tuesday, F1 CEO Chase Carey said he considered the statement "strange" and insisted it would have no impact on F1's existing plans for the future.
