The French Grand Prix has been dropped from the 2004 Formula One calendar, race organisers have said.

The removal of the Magny-Cours race from its 11 July date has prompting suggestions that the British Grand Prix may be pushed back one week from 4 July, when it clashes with the finals of Euro 2004 and Wimbledon.
French officials said on Saturday that they had signed a fresh five-year deal with Formula One chief Bernie Ecclestone to restore the event to Magny-Cours from 2005.
"We're having a break in 2004, in agreement with Ecclestone, and we have signed a contract from 2005 to 2009, with the possibility of adding another five years," said circuit boss Roland Hodel.
"In 2004 everyone who loves motor sport has to launch into action to bring in all the partnerships which are necessary for us to have Formula One back again."
On Friday, Marcel Charmant, president of the Nievre regional authority, revealed that the French Grand Prix had been cancelled.
"It is not possible to give Ecclestone the guarantees he requires for the finance of the race in 2004," he said.
Ecclestone was demanding unpaid fees of £6.5m.
Ralf Schumacher won this year's race at Magny-Cours, which has hosted the French Grand Prix since 1991.
