Anand Jain, director of a Reliance company IPCL [Get Quote] and a close confidant of RIL chairman Mukesh Ambani, was the target of a letter sent by Anil to his brother. Anil had attacked Jain earlier this month by accusing him of conspiring to divide the family.

The fresh attack from the younger brother comes amid reports that a formula for legal separation was being worked out at the behest of Kokila Ben, the widow of Reliance founder Dhirubhai Ambani, by ICICI Bank [Get Quote] chairman K V Kamath.

Referring to his earlier letter on January 3, where he had tendered resignation as vice-chairman of IPCL, Anil said in his latest communication that Anand Jain was a director on the Board of the erstwhile PSU acquired by the group in 2002 and was also acting as a distributor of the company.

 The Reliance 'ownership issue'

"This is obvious conflict of interest," the younger brother said in his letter to the chairman of IPCL, Mukesh Ambani and requested guidance on the issue, according to sources close to Anil Ambani.

Through his first letter, where he had said it would be below his dignity to be on the same board as Anand Jain, and through the latest communication, Anil is putting pressure on elder brother to make a choice between him and Jain.

It may be recalled that Mukesh had gone to the residence of M L Bhakta a day after the founder director of Reliance Industries had resigned from the Board after the differences between the two brothers had become public in November. But the RIL chairman has not made such a gesture after Anil resigned from IPCL board and this reflected from his letter today.
