Malvinder Mohan Singh, the last remaining family member to head India's largest pharmaceutical company, has severed his ties with the business his grandfather founded in 1961.
In a statement, the company said he was stepping down from the positions of chairman, CEO and managing director with immediate effect. He will be replaced by Atul Sobti, Ranbaxy's COO.
The news comes almost exactly one year after the Singh family sold their 35% stake in the business to Japanese pharmaceutical giant Daiichi Sankyo.
