New Delhi: A day after closing down its controversial Free Basics programme, Facebook India MD Kirthiga Reddy on Friday stepped down from her current role. The social networking giant has started looking for a successor to Reddy, who would move to Facebook's headquarters in the US in the next 6-12 months. Facebook on Thursday shut down Free Basics in India, days after TRAI barred operators from charging discriminatory rates for Internet access based on content. PTI
