Formula 1 drivers have called on the sport's chiefs to change the way that they approach decision-making in an almost unprecedented open letter.
The letter from the Grand Prix Drivers' Association (GPDA), which is signed off by Britain's Jenson Button and four-time world champion Sebastian Vettel, demands an overhaul to the "obsolete" and "ill-structured" decision-making process.
"We feel that some recent rule changes - on both the sporting and technical side, and including some business directions - are disruptive, do not address the bigger issues our sport is facing and in some cases could jeopardise its future success," the letter read.
"The drivers have come to the conclusion that the decision-making process in the sport is obsolete and ill-structured and prevents progress being made. Indeed, it can sometimes lead to just the opposite, a gridlock. This reflects negatively on our sport, prevents it being fit for the next generation of fans and compromises further global growth.
"We would like to request and urge the owners and all stakeholders of Formula 1 to consider restructuring its own governance. The future directions and decisions of F1, be they short or long term, sporting, technical or business orientated should be based on a clear master plan. Such plan should reflect the principles and core values of Formula 1."
The letter comes days after F1 scrapped a new qualifying system that was used in the opening race of the 2016 season in Australia but swifty came in for criticism after the track was left empty for several minutes.
