Indian supermarket chain owner Ramesh Lahoti says he has every reason to fear encroachment by global retailers — since 2007 he has had to close five of his M.K Retail stores in the southern city of Bangalore due to stiff competition from Germany's METRO Cash & Carry.

If Wal-Mart, the world's biggest retailer, sets up shop near his existing eight stores in India's third most populous city, Lahoti says the future of the family-run business will be in jeopardy.
