Kokilaben Ambani, widow of the founder of the Reliance empire, on Saturday emerged as the likely arbiter in the battle between her two sons with the elder one Mukesh leaving 'all settlement issues' to her, a path his brother Anil had favoured a few days ago.

In an important turn in the battle for the control of the Rs 90,000-crore group, founded more than a quarter century ago by Dhirubhai Ambani, a spokesperson for Mukesh said on Saturday night that he would abide by whatever decision she takes.

Asked if this has been conveyed to Anil also, he replied in the negative saying there was no communication from the younger brother who had been talking through the media.

"Mukesh Ambani has not sought any legal separation. This is a false propaganda. He has left the entire matter in the hands of his mother (Kokilaben) and whatever she decides he will abide by it," the spokesperson told PTI.

Earlier in the day, sources in the Anil camp had accused Mukesh of turning down the efforts to stay united and seeking a 'formal legal separation'.

This was described by Mukesh's spokesman as 'a figment of imagination, baseless and nonsensical'.

In October 2002, the two brothers and their sisters, Dipti and Neena, along with their mother had signed a 'Deed of Release' leaving the entire property and assets of Dhirubhai, who died without a will, to Kokilaben.

When asked about the ongoing tussle in the Ambani family, spiritual guru Bhai Shri Oza said, "Thakurji ki kripa se sab accha hoga (By the grace of God, everything would be fine).
