Marussia have confirmed that Timo Glock is to leave the team ahead of the 2013 season.
The team stated that it had parted company with Glock by mutual consent and with immediate effect. Marussia appeared to suggest that tough economic conditions were behind the split.
There had been speculation over the weekend that the German driver was to leave the team after a report was published in Sport Bild.
Glock joined Marussia in 2010 when the team made its F1 debut and later extended his contract until the end of 2014.
Despite leaving the team Glock wished them luck but it is not yet know where he will end up next season with suggestions he could race in DTM.
Marussia recently signed British driver Max Chilton to race for the outfit in 2013 where he was expected to join Glock.
Glock’s departure means that there now are four seats to fill before the start of the 2013 season with Caterham and Force India yet to announce drivers.
