The Indian Grand Prix is unlikely to be included in the 2014 Formula 1 calendar, according to Bernie Ecclestone.
The event made its debut in 2011, but teams have been constantly concerned about taxation issues when entering the country. India's government has not granted a custom exemption to the teams, as it does not consider F1 to be a sport.
"Is India going to happen next year? Probably not," Ecclestone told Reuters in Hungary. "[It's] very political."
Russia and Austria will be joining what is set to be a 20-race calendar next year. India will host its third grand prix in October this year.
Earlier this year, race organizers denied as "baseless and malicious" rumors about the event being in doubt.
