He will replace Chris Hunton, who is leaving the agency by the end of next week. Whyte takes up the job on May 1.
Whyte moves across from McCann's European operation, where he has been client services diector since the end of 2002. The appointment was made by the agency's chairman Rupert Howell.
Whyte was ousted from Leo Burnett by its former worldwide chief executive Steve Gatfield in March 2002. He was replaced with the agency's current chief executive Bruce Haines.
