The British and French Grands Prix in July have been included on a 19-race calendar, with teams entitled to compensation for attending more than 17.

Team boss Frank Williams said this month that all of the teams had agreed to the expansion except world champions Ferrari, who wanted more money.

Brawn, speaking after delivering a lecture on motorsport safety at the Autosport International show in Birmingham, said he was sure Ferrari would be at both races.

But he said the designation of Britain and France as the extra races rather than newcomers China, Bahrain or Turkey would hit teams in the pocket.

"We want to race at Silverstone and we want to race at Magny-Cours," he said. "I am an Englishman and (team boss) Jean Todt is a Frenchman.

"We believe that the 18th and 19th races are either Bahrain and Turkey or China and Turkey," he added. "It is completely wrong that Magny-Cours and Silverstone were manipulated into being the 18th and 19th races.

"The income from those races in China, Bahrain and Turkey is very, very substantial. That is the money that should be shared among the teams, not the contribution that Magny-Cours and Silverstone are making."
