Top Sir Dorabji Tata Trust (SDTT) trustees have penned a strongly worded letter, calling out fellow trustees Venu Srinivasan and Vijay Singh for "undermining board resolutions" through their independent views that support the public listing of Tata Sons, the holding entity of the salt-to-software conglomerate Tata Group. The letter, assessed by NDTV Profit, shows a significant escalation of internal friction within Tata Trusts, as the SDTT trustees have accused Srinavasan and Singh of "breaching fiduciary duties".
