The executive, Matt Wiant, had been senior vice president of marketing for equity brands. He left the company in a restructuring, the spokesman said.
His temporary replacement is Simon Cunningham, vice president of development brands. Mr. Cunningham will serve as acting regional marketing director, reporting to Allied Domecq's president, Richard Turner.
The agencies could not be reached for comment.
Allied, the country's fifth-largest spirits company, is trying to align its brands under one global strategy.
The company had consolidated U.S. media planning for its liquor brands at its media buying agency, Zenith Media, New York.
Separately, Allied's partner for two ready-to-drink malt beverages, Miller Brewing Co., today announced the names of the drinks. A Stolichnaya beverage is called Stoli Citrona, and a Sauza tequila drink is Sauza Diablo.
