Andy Soucek has parted company with the Virgin Racing team, for which he had been acting as test and reserve driver.
The 2009 Formula 2 champion took on the role after original candidate Alvaro Parente ran into funding difficulties, and attended the early rounds of the Formula 1 season with the team, although the testing ban meant he had no opportunity to drive the car.
Soucek's departure still leaves Virgin with Luiz Razia as a test driver.
Soucek says he is working on alternative routes toward an F1 race seat for 2011. He recently returned to competition with the Sporting team in Superleague Formula.
