The reasons for Rupa Gurunath’s resignation as President of the Tamil Nadu Cricket Association (TNCA) run deeper than the BCCI resolution citing a conflict of interest. This is one of the battles former BCCI and ICC chief honcho N Srinivasan is fighting to retain control over his billion-dollar brand — CSK. Earlier, Radhakishan Damania of DMart fame picked up a nearly 20% stake in India Cements. Was it to wrest control? Currently held by Indian Cements Shareholders Group Trust, CSK would become vulnerable if Srini is unable to ward off raids on India Cements. His plan is to move daughter Rupa to a key post in CSK after restructuring its ownership so that the IPL franchise stays in the family, regardless of developments in India Cements’ shareholding pattern. There is still a lot of fight left in the old cricket lover and corporate czar who once fought a pitched battle to wrest back control of the cement company with the help of Murasoli Maran. But if the tide turns against him, Srini would rather keep CSK in the family and leave the TNCA presidency to the DMK first family. V Sabareesan, the son-in-law of Tamil Nadu CM MK Stalin, is one of the frontrunners for the post after it was found that son Udhayanidhi was ineligible as he holds public office as an MLA.
