Delhi Chief Minister Arvind Kejriwal on Saturday alleged that Prime Minister Narendra Modi was killing constitutional institutions one by one."This PM (Prime Minister) is killing institutions one by one - RBI (Reserve Bank of India), CBI (Central Bureau of Investigation), universities and now judiciary. What India achieved in 65 years will be undone by him in five years," Kejriwal tweeted.His comments came in response to an article published in a news portal which said that India had only 58 per cent of the High Court judges than it should.
