After a stint of almost two years, Sandip Tarkas has decided to call it a day at the Reliance ADA Group. He was in-charge of media for the whole group as Head – Media. Tarkas has already put in his papers, and would be serving his notice period at R-ADAG till early January 2008. Details on his next destination were not available at the time of filing this story. It may also be recalled that M Suku had recently joined R-ADAG in a group role. Speculation is doing the rounds that Suku may be given Tarkas’ role. However, no confirmation was available on this.
