Romain Grosjean has replaced Jenson Button as a director of the Grand Prix Drivers Association (GPDA), joining Sebastian Vettel and Alex Wurz as the group's figureheads.
The GPDA exits as the Formula One drivers' trade union and has a long history of campaigning for safety improvements in the sport. After retiring from full-time participation in F1 last year, Button opted to stand down from his position as director and at the Russian Grand Prix the members of the GPDA voted for Grosjean to replace him.
Grosjean will work alongside fellow director Vettel and under the chairmanship of former F1-driver Wurz.
