David Higgins, CEO of the Olympic Delivery Authority (ODA), has quit in order to join Network Rail.
He will leave in February 2011, and will be replaced by the ODA's current finance director Dennis Hone.
Last year Higgins was awarded a bonus of £200K (a large part of which he deferred), on top of his £384K salary.
Is this really the best time for him to leave?
