BigT wants bigger pie in India, but it just can't seem to bypass Mukesh Ambani

Ambani’s Reliance Industries NSE 0.25 % Ltd. is said to be offering to sell a stake of about $20 billion in its retail business to Amazon.com Inc.
If Ambani succeeds in pulling off such a deal, it would mark another victory for the billionaire, who in recent months has secured $20 billion of investment in his digital unit from marquee names including Facebook Inc. and Google Inc.
