Michael and Tomlinson to leave Williams at the end of the season

Williams F1 today announced that Technical Director, Sam Michael, and Chief Aerodynamicist, Jon Tomlinson, have resigned from their positions within the company, to take effect at the end of 2011.

Frank Williams, Team Principal, said: "Both Sam and Jon are talented and driven people who have worked hard for Williams over 10 and five years respectively. Nonetheless, they have recognised that the team’s performance is not at the level that it needs to be and have resigned in order to give the team the opportunity to regroup and undertake the changes necessary to get back to the front of the grid.

"Both will continue to work in their present positions through until the end of the year to ensure that the team maintains focus and momentum during the 2011 season. We are very grateful to Sam and to Jon for their professional approach."
