Formula 1: Force India chief's finance concern

Formula 1 needs spending controls to avoid teams "racing themselves", Force India chief operating officer Otmar Szafnauer tells BBC Look East.

There are concerns over the sustainability of F1 teams, with Caterham failing to complete the 2014 season, and Marussia revived as Manor Marussia after going into administration.

Silverstone-based Force India are one of 10 teams lined up for the 2015 season, which starts in Australia on 15 March.
