USGP faces an uncertain future

The US grand prix faces an uncertain future. Tony George, chief executive of the Indianapolis circuit which hosts the race, blamed uncertainty within the sport after renewing its contract for only one event.

George has signed a one-year, $20m (£10.6m) deal with Bernie Ecclestone, the formula one commercial rights holder.

"It seemed appropriate to see how things shake out," said George, referring to the expiry next year of the Concorde agreement which regulates formula one. There are too many unanswered questions to commit any longer than that." The Guardian
