"This has been an unfortunate and challenging situation for Binny, his family and Flipkart," the e-commerce provider said in a separate internal note.Kalyan Krishnamurthy, currently chief of the Flipkart division, will report directly to the board, Walmart said.

As recently as October, he said in an interview that he was still in charge of Flipkart and would remain group CEO after the Walmart acquisition."Both sides are convinced that keeping Flipkart running independently makes the most sense," he told Bloomberg.
