"A supermarket company has emerged as a serious bidder for the Market Basket chain, complicating Arthur T. Demoulas’s effort to buy out rival family members and take complete control of the grocery empire, according to people briefed on the negotiations.
The Belgium-based parent of Hannaford Bros. Co. is offering to buy part or all of Market Basket, which competes with it in markets throughout New England, said these people, who were not authorized to speak publicly on the matter. A spokesman for Hannaford could not be reached for comment Thursday."
