Tata Motors President (International Business) Ranjit Yadav, who joined the automaker from Korean telecom giant Samsung Electronics in 2012, has put in his papers.

While the reason for the resignation was not immediately known, industry sources attributed it to “differences of opinion” with the top bosses at Tata Motors. Certain media reports said Yadav was sidelined after the company brought in Mayank Pareek, a Maruti Suzuki veteran, to head the domestic unit.

While a Tata Motors spokesperson said the company had “no comments to offer”, Yadav could not be reached immediately for comments.

Yadav had joined Tata Motors in September 2012 to revive the falling sales at the country’s largest automotive manufacturer, including that of Tata Nano. Following a change in portfolios in September last year, Yadav was put in charge of the company's international car markets.

He had joined as president, Passenger Vehicles Business Unit.

At Samsung, he was the country head Country Head (Mobile and IT), and prior his stint with the Korean company, he was with Hewlett-Packard. Yadav had also worked with companies such as Philips Electronics and Hindustan Unilever.

The timing of Yadav’s exit has surprised the industry, as Tata Motors with its recent launch of hatchback Bolt and compact sedan Zest, signaled its intent to regain its lost ground in passenger car market segment.
