Mukesh Ambani-led Reliance Industry has questioned the sincerity of Anil Ambani's peace offer saying conduct of his group makes it difficult to believe if he had a real change of heart. Welcoming Anil's statement to reach out his estranged elder brother Mukesh, RIL said in a statement that it hopes, it is a positive change in the negative, calumnious and malafide campaign launched by Anil Ambani group against RIL. The company statement further said, the conduct of R-ADAG so far makes it difficult for RIL to believe that Anil Ambani had a real change of heart. For last many years Anil Ambani had indulged in a malicious campaign against RIL and its Chairman. The campaign reached its nadir in recent months through a vicious series of advertisements unprecedented in India's corporate history. Anil made this offer after returning from pilgrimage to Kedarnath and Badrinath.
