Williams have confirmed that Mark Gillan, an engineer key to the teams revival, has quit in order to spend more time with his family.
Gillan joined the outfit last season alongside technical director Mike Coughlan and head of aerodynamics Jason Somerville in order to halt the teams decline.
The team won its first race since the 2004 season thanks to Pastor Maldonado’s Spanish GP victory. Whilst the team only managed one better this season by finishing eighth in the championship, their car was capable of much more.
The former McLaren, Jaguar, Red Bull and Toyota employee is now on ‘gardening leave’ having left the outfit earlier this month.
