Billionaire Gerry Harvey, CEO of Harvey Norman , has offered to run supermarket giant Coles Myer for free after giving his harsh diagnosis of the grocer's performance during an interview. Speaking on the Nine Network's Business Sunday program, Harvey argued that Coles issuing a profit warning in June was a tragedy. Furthermore, he said that the problems at the "lousy" retailer are caused by mismanagement, and that the board needs to be "revamped."
