The government- run defence firm BEML, and its chairman VRS Natarajan, are spawning a series of embarrassing controversies for the government. The latest revolves around an order from the Company Law Board in Chennai which says that BEML (Bharat Earth Movers Ltd) and Mr Natarajan suppressed documents to disguise Mr Natarajan's mismanagement in a joint venture in the mining sector. In 2007, BEML teamed up with a private firm named Midwest Granite to form a joint venture called BEML-Midwest Ltd to explore the mining sector.
