French hypermarket group Auchan is mulling the acquisition of Simon Properties' stake in Gallerie Commerciali Italia (GCI) after the US-based retail specialist failed to find a buyer for the asset. According to well-informed market sources, in the past few months all interested parties have withdrawn from the acquisition in GCI, which owns and manages 47 shopping centres in Italy. Auchan already owns 51% of the company through its Immochan unit.
