British Grand Prix future not a certainty warns Ecclestone

F1 supremo Bernie Ecclestone has hit out at European countries that don't spend more to safeguard their future on the F1 calendar.

Ecclestone was asked by Top Gear which grands prix races he most regrets that fell off the calendar, and answered: "Two races we've lost which I'm genuinely upset about were India and Turkey."

However, the sport has also lost France, Monza's race was in doubt for months and the future of the German grand prix is in doubt.

"It's the same as in England," Ecclestone insisted. "Silverstone is not, I'd say, super-safe - quite the opposite. These circuits don't need a lot of money to make them safe."

"It's disappointing to think that all these countries spend a lot of money trying to get the Olympics ... and nobody makes any money out of. Yet, for the small amount of money they could (spend on) a formula one race, they don't want to do it," he added.
