The controlling stake in food retailer Blue Square Israel is being sought by a group of foreign investors led by Deutsche Bank. According to a report in Yediot Ahronot, the group could consist of, among others, the Bank Leumi-Paz group and the Benny Gaon-Shamrock group. The newspaper points out however that Deutsche Bank has represented French supermarket giant Casino Guichard in the past with regard to business in Israel.
