The Middle East retailing juggernaut-the Dubai-headquartered Landmark Group that he founded in 1973 with one store in Bahrain-generates more than $5 billion revenues annually from 1,800 stores across the Middle East, Africa and India. It reportedly plans to open 50 more stores by 2015. After ending a two-year alliance with France's Groupe Auchan that operated 13 hypermarkets in India, Landmark has teamed up with Dutch retailer SPAR. The privately-held group, which wife Renuka helps him run, also has interests in hotels, health care, fitness gyms and confectionery.
