Two top executives leave GM.

The New York Times (4/15, Vlasic, Subscription Publication, 9.65M) reports on the departure from General Motors of Selim Bingol, senior vice president for global communications and public policy, and Melissa Howell, senior vice president for global human resources. Their departures are seen as “the first major executive change” under CEO Mary T. Barra. GM spokesman Greg Martin, said that they are “unrelated to the recall of Chevrolet Cobalts, Saturn Ions and other cars for defective ignition switches.” No replacement has been announced for Bingol, but John J. Quattrone will replace Howell. He was worked at GM since 1975.
