The Confederation of All India Traders (CAIT) has filed a petition before the Competition Commission of India (CCI) seeking to block Amazon's deal to acquire 100% shareholding in Cloudtail. "The petition provides evidence to show Cloudtail charges less fees/commission and is a preferential seller," CAIT said. Cloudtail is a joint venture between Amazon and NR Narayana Murthy's Catamaran Ventures.
