Facing flak from the Left parties for Wal-Mart's entry into the Indian retail market, Rajan Bharti Mittal, joint managing director of Bharti Enterprises, today said its tie-up with the US firm was "as per guidelines"."Bharati will manage the front-end 100%, while Wal-Mart will provide support at the back-end, logistics and supply chain. The deal is as per the (government) guidelines," Mittal said on the sidelines of a FICCI function in New Delhi today.Asked if the deal provided Wal-Mart a back door entry into the Indian retail market, he said it was not the case and Wal-Mart will be doing the same as other global retailers like Germany-based Metro were doing in the country.Rajan Mittal, however, declined to comment on the reaction of the Left parties to the Bharti, Wal-Mart deal.Left parties had opposed Wal-Mart's entry into India and alleged that the retail giant's joint venture with Bharti would enable FDI entry into the retail sector through the back door.
