Next year's proposed Argentinian MotoGP round has dropped off the provisional calendar after political problems involving the Repsol company made it virtually impossible for some riders and team employees to travel to the South American country.

The race, which had been scheduled for April 14, will now not take place after the country's government nationalised Repsol's Argentian arm. The cancellation means the Qatar race and the second meeting at Austin's next track will open the 2013 season.

Qatar has been moved into an April 7 slot which means there is only a two week gap between it and the Austin race. The rest of the calendar is unaffected but the Jerez round is still subject to contract.
