The Trusts had unanimously resolved to recommend extending his tenure by five years. When the proposal reached the Tata Sons board it did not carry unanimously — reportedly a single director withheld support — and the decision was deferred. Rather than leave the leadership question open through his remaining months, Chandrasekaran asked the board to move to selecting a successor. The disagreement sits within a wider set of differences between Tata Sons and Tata Trusts over board representation, the group's strategic direction, and the proposed exit of minority shareholder the Shapoorji Pallonji Group.

Note first what has NOT happened: he has not left. He remains chairman until February 2027, and the headline framing of 'stepping down' overstates the immediacy. What has changed is that the succession is now open. Under his chairmanship the group expanded into semiconductors, electronics, aviation and defence, and took on the Air India turnaround. For exam purposes the transferable content is structural — the Trusts-holding-company arrangement, and how shareholder and board disagreement plays out in a group of this scale — rather than the personalities involved.
