A split in the conglomerate

Following their father's death in 2002, the public feud of the Ambani brothers over control of the Reliance resulted in a split in the conglomerate. Mukesh Ambani, the richest man in the country, controls oil-to-telecoms powerhouse Reliance Industries.

Was Anil bailed out by Mukesh?

The apex court had held Anil Ambani in contempt last month for not paying Ericsson's dues even though he had enough money to pay it off. The SC threatened to send him, along with the chairmen of Reliance Telecom and Reliance Infratel— Satish Seth and Chhaya Virani— to pay the dues within four weeks or face a three-month prison sentence for contempt of court.

While it is unclear how Mukesh helped Anil, he seems to have provided some kind of support to his younger brother to pay off a debt of Rs 550 crore.
