Senna dropped for Silverstone

Bruno Senna has been dropped by Hispania Racing for this weekend's British Grand Prix at Silverstone.

Senna, nephew of late three-times world champion Ayrton, will be replaced by the team's test and reserve driver Sakon Yamamoto.

It is understood Senna's release is due to a lack of sponsorship funds arriving on time, although Hispania team principal Colin Kolles is due to make clear the situation.
