Union minister Hardeep Singh Puri reacted after AAP chief Arvind Kejriwal alleged that BJP is planning 'Operation Lotus' to manipulate the Delhi voter list ahead of Assembly elections. "I think when Arvind Kejriwal was in 'state hospitality', his mental equilibrium got disturbed," Puri said. "What is his vision- disruption? Kejriwal is left with very little time," he added.
