Campeau Corp. said Monday that Robert Campeau will resume his position as Campeau chairman and will become interim chairman and chief executive of Allied Stores, which merged with the Toronto-based real estate company on Dec. 31.

Howard E. Hassler, Allied’s chief financial officer, will become president and chief operating officer of New York-based Allied Stores.

Campeau will immediately succeed Thomas M. Macioce, who headed Allied Stores and who became chairman of Campeau Corp. when the merger was completed.

Hassler will replace James A. Walsh on Feb. 1. Macioce and Walsh will resign from the boards of Campeau and Allied. The management changes were made in light of the recently announced restructuring of Allied, which will sell 16 of the company’s 24 divisions, a spokesman for Campeau said.

“It was felt this was the best management team to go with,” the spokesman said. “The Macioce-Walsh team presided over a much different company.”
