Bernie Ecclestone has admitted the possibility that Barcelona could lose the Spanish grand prix.
Circuit de Catalunya officials recently rubbished reports that F1′s other Spanish host, Valencia, had proposed to replace Barcelona on the calendar from 2012.

“Two weeks ago it looked like Barcelona was not going to have the race any more, and not just next year,” F1 chief executive Ecclestone told Spain’s TV3 television before departing the Nurburgring.

He then admitted the possibility that Barcelona and Valencia might from now on annually alternate the running of a single Spanish grand prix.

Ecclestone, 80, also said Spa-Francorchamps and France might similarly alternate the hosting rights to a single annual calendar slot in the future.

“The negotiations to alternate Barcelona and Valencia are still on,” he is quoted as saying by EFE news agency.
