Denouncing booking of its senior leader Hilal Akbar Lone under the Unlawful Activities (Prevention) Act, the National Conference (NC) on Wednesday alleged that the government was finding sedition under every stone to silence the Opposition. Lone, the son of NC MP from Baramulla Akbar Lone, was on Tuesday booked under the UAPA for alleged 'hate speech' at a rally during the District Development Council (DDC) elections last year in north Kashmir.
