Ross Brawn does not expect his team's Formula One cars to carry the sponsorship of Sir Richard Branson's Virgin Group next season. Virgin agreed to sponsor the team just before the season began in March, just weeks after Brawn had secured their survival in the wake of Honda's decision to pull out of the sport. The decision paid off as Jenson Button took the drivers' championship, with his efforts and those of team-mate Rubens Barrichello also enough for Brawn to take the constructors' title. But team principal Brawn has conceded that he does not expect the Virgin partnership to continue as his all-conquering team look to repeat their success in 2010. "We had a great year with Virgin but they have different ambitions next year so it's unlikely you will see their name on the car next year," he said.
