Escalating tensions with his elder brother Mukesh Ambani in the battle over the Reliance empire, Anil has sought a meeting of the board of directors of Reliance Industries Limited to discuss the 'recent developments,' including RIL's investment of Rs 12,000 crore (Rs 120 billion) in Reliance Infocomm.

Anil, in his letter, has also sought discussion on the resignation of 'our most esteemed' M L Bhakta, one of the closest friends and associates of their late father Dhirubhai Ambani (who had quit the RIL board), and the recent letter from the board of directors of Reliance Energy Ltd headed by him to the RIL board.

Acting on the letter written by Anil on December 6, Vinod Ambani, RIL company secretary, has written to all the members of the board of directors seeking a suitable date for convening the meeting.

Anil said in his letter that it was with 'great sadness and anguish' that he had witnessed the events of the last three weeks which had affected the image of 'our company' and the interests of over 30 lakh (3 million) shareholders and all other stakeholders.

"Dhirubhai, to most of us, was not just the chairman of the board, but more importantly a close personal friend, a confidante, a teacher, a guru and a guide. Dhirubhai, the father of the Indian capital markets, wished, above all else, to maximise value for his first, last and only constituency -- Dhirubhai's real family of over 30 lakh shareholders," he said.

"In the absence of his guiding hand and in pursuance of what I am sure he would have wished us to do, I thought I could do no better than bring to your attention the following matters that need our collective wisdom," he said in the letter to the RIL board of directors listing the three issues.
