The Tata Sons board meeting has been delayed to May 16 with no explanation. The listing of Tata Sons is a top concern after the RBI labeled it as a shadow bank and increased supervision. There is a dispute among trustees, with Noel Tata against the listing while Venu Srinivasan and Vijay Singh support it. Ex-trustee Mehli Mistry stands by his decision to vote against Srinivasan and Singh.
