Mukhopadhyay would report to Tata Sons Chairman N Chandrasekaran, who was elevated to lead the over USD 100 billion group in January this year after the unceremonious sacking of Cyrus Mistry.
"We wish to inform you that Suprakash Mukhopadhyay, Global Treasury Head and Company Secretary will be transferred to Tata Sons Ltd and will join the Chairman's office reporting the Chairman," the company said.
It further added: "The board has appointed Rajendra Moholkar as the Company Secretary to take over from Suprakash Mukhopadhyay on his relinquishing the office on April 24, 2017."
