Max Mosley has forcast a difficult period is ahead for Formula One, as Wednesday's peace deal between the FIA and FOTA is cast into doubt. In a previous letter to member clubs of the FIA, Mosley called on them to elect a strong president to stave off the FOTA threat to the FIA, with another letter from Mosley, this time addressed to the World Motor Sport Council (WMSC) further elaborating on the threat FOTA poses to the FIA.

In what is seen as a move to return to the political fold at the FIA at the end of his current term in October, Mosley pointed to the FIA's involvement in areas outside motorsport in addressing the WMSC.

“In addition to motor sport, the FIA has to defend the interests of the motorist in areas such as road safety and the environment and even basic things like access to technical information for independent garages. This often brings us into conflict with the car industry,” wrote Mosley. “When we started EuroNCAP, one of the major manufacturers threatened to quit Formula 1 if we did not abandon our activities. The FIA has to be free to confront the car industry whenever necessary.”

Mosley continued by writing that he had been looking forward to a peaceful summer following a hectic 12 months in his personal life, only for FOTA chairman Luca di Montezemolo to issue 'deliberately misleading' comments to the media, contravening the deal that was brokered on Wednesday in Paris. 'Intolerable' was how Mosley described the situation.

“It is disappointing that Montezemolo did not keep his part of the bargain we made last Wednesday. I had anyway decided not to offer myself for re-election next October and, given what I have had to contend with during the last 12 months, I needed a peaceful summer before starting a more leisurely existence,” he continued. “The compromise we found was therefore acceptable to me personally and seemed in the overall interests of Formula 1. But when FOTA falsely claimed that they had ousted me and imposed their will on the FIA, the situation became intolerable.”

The FIA president also mocked the teams' plans for an independent court of appeal, claiming that a manufacturer team lobbied him to declare the "double diffuser" illegal.

“We have heard a lot from FOTA about an independent court of appeal. Yet during the controversy over the "double diffuser", a manufacturer team repeatedly lobbied me (wholly improperly) to intervene with the FIA Court of Appeal and have the double diffuser declared illegal,” he revealed. “The FIA Court would never listen to such an approach but it shows that for the team in question, "independent" means independent of the other teams and under the control of particular interests.”

In concluding his letter, Mosley acknowledged that short-term problems may be a result of the ongoing difficulties, likely to refer to the possibility of FOTA reopening their breakaway series plans. However, he insisted that the difficult times the sport is facing is no reason to hand power over to the teams.

“No doubt we face a difficult period. This may well result in short-term problems in Formula 1. It is possible that FOTA will set up an independent series. That is their right, provided they do so under the International Sporting Code.

“But the Formula 1 World Championship will continue to be run by the FIA as it has been for 60 years. The Championship has had difficult times in the past and no doubt will again in the future but that is no reason to hand control to an outside body, still less one with little or no understanding of sporting ethics and under the control of an industry we have constantly to monitor.”
