Ford Motor Co. Vice President and Chief of Staff Steve Hamp will leave his post by year-end, a spokesman confirms.

No official announcement on Hamp’s departure has been made, the spokesman says, but “because of leaks to the press,” Hamp decided to go public with his decision.

Prior to his current position, Hamp, 58, served as president of The Henry Ford in Dearborn. Hamp also is the brother-in-law of Executive Chairman Bill Ford.

Hamp has not revealed his future plans, the spokesman says.

Hamp is the latest high-ranking official to leave the auto maker. In the past several weeks, Ford has announced the imminent departures of A.J. Wagner, president-Ford Motor Credit Co.; vice president Anne Stevens, executive vice president and chief operating officer-The Americas; and David Szczupak, group vice president, manufacturing-The Americas.
