Tata Motors announced that the head of its passenger car unit had resigned from the company.

Rajiv Dube, who had served for 27 years, was a key player when Tata entered India’s passenger car market with the Indica in 1998 and with the introduction of the low-cost Nano last year.

Tata said in a statement that S Krishnan, who currently heads up  the sales, marketing and support functions for commercial vehicles, will take on additional charge of the premier car division and Girish Wagh, head of small car projects, will now be also responsible for passenger car manufacturing and product development.
